Used Tacoma, sludged engine

These are great updates! Good reporting and a great change from "Posting and ghosting" a problem!

 

@Torspd I'll tell the rain you're asking about it (if it lets me get a word in)! If I'm being candid, I actually love the crazy weather. It ruins our plans, threatens our home, and freaks out our dogs, and man, it keeps things interesting.

With regards to the tensioner pulley, I'll give it another look! I greatly appreciate the P/N! Bearing shopping is a real headache. My last bearing job was for our LG frontload washing machine. It sounded like a jet taking off. I put timken bearings in it overcompressed and botched it to hell, wound up swapping the whole drum, motor, seal, and door assembly with one from a scrapped machine our neighbor had sitting in their car port.

Slightly smaller drum, hence the need for extras. But it's working like a charm!

 

The inclement weather challenges our skill for survival and prepping. For that reason strangley enough, I like the challenge.

 

Your reasoning is much more admirable than mine. I find that there's some strange satisfaction to working in the perfectly wrong conditions. Maybe it's that you don't have to worry about things going afoul, or that limitations are set by environment rather than competence alone.

I wasn't feeling all that great today, so I skipped. I did get to see that the Mahle timing cover gasket set does not include any of the 4 standard o-rings needed for the job (maybe folks just glob on the silicone?)
I couldn't find one of the old ones either, so I took the trip to Ace hardware again and brought the whole timing cover in hand. The gent there helped me fit everything up, but not all of the o-rings received had baggies, thus no labels.

I'll be measuring them some time soon - tomorrow or the next day, and I'll post up all my measurements so that the next person will have an easier time. Until then, I guess the governor declared a preemptive state of emergency for tomorrow's storm. Wish me luck!

 

Read through the whole thread and impressed with your thoroughness and skills and not giving up. Post a video after you crank it up. Hope you are prepped for the storm and bless you all down there. I grew up in Panama City and watched Michael as it walloped my brothers and friends there. Let us hear from you after it all settles down.

 

Great work OP...both on the repair and the documentation. This will be of value to the next guy doing something similar.

 

I'm really grateful to hear that stuff I've contributed is being considered significant! I'll do my best to live up to the standard set. You guys have been awesome. It's been really cool getting to bounce ideas off of you and get second opinions on multiple aspects of this challenging project.

So, the hurricane was a flop for us. The weather we received was actually calmer than usual, although we were visited by two small, very angry birds. Kept flying all around the front of our house squawking. I had to squirt 'em with a hose to make them leave.

I'm hoping to get to the timing cover today. So far I only got to do some work on the transmission mount. The bolt that passes through the rubber of it had broken loose - OEM replacement mount only ~2 years old.

Here I'm showing off the original fastener. It's got compressed ends like a rivet - had to drill it out to remove it.


Got the fastener I actually wanted installed

Cut to fit and red lock-tite


Not sure why the old fastener broke loose, but this one's a big 10.9 I use with the engine hoist. If rattling caused by the nut/washer becomes annoying I'll replace the mount.

OK! Errands and chores are done for now, time to measure some O-rings

Also, @Arrowshot , thank you for the kind words. I'm terribly sorry to hear that one of the past hurricanes affected your friends and family. Natural disasters like that are positively terrifying, and all the more when you have an idea of what to do but lack the resources to do it (like us). My heart goes out to all the families impacted by such occurrences.

I'll be sure to post up a video soon. Should be just a couple days now.

 

Okay, here goes.
O-ring #1, upper right - loose fit


OD: ~ 1.389"


ID: ~ 1.2"


Standard thickness: ~ 0.1"


O-ring #2, Upper left hand side - tight fit


OD: ~ 1.032"


ID: ~ 0.841"


Standard thickness: ~ 0.1"


O-ring #3, Lower right - loose fit


OD: ~ 1.032"


ID: ~ 0.841"


Standard thickness: ~ 0.091" (could be 0.1 also)


O-ring #4, Bottom/oil pump - tight fit
Danco #43, ~ ID: 1-1/8", OD: ~ 1-3/8" listed on bag. This one is thick.


Thickness: ~ 0.134"


Jeez. That was obnoxious to do
But that's all the O-rings you'll need outside of the mahle gasket kit. Normally when I put in o-rings I'll grease them with "red rubber grease", or you could use vaseline (purposed to hold in place, keep from binding/ripping during assembly) BUT this whole cover is held on by silicone so I'm gonna silicone all of them just as they were when I removed the cover.

Now to clean up the oil pump and reassemble it.

** Edit: I wanted to add that when I referred to the fitment of each o-ring (tight or loose) I meant their inner diameter fit tightly or loosely. If somebody has a timing job coming up and hops on mcmastercarr I doubt they'll see any o-rings that have identical measurements to mine (they'll be measured more carefully I'm sure). On the loose fit ones, you can pick up some that are ever so slightly smaller. On the two tightly fit ones, err on the side of getting a larger I.D. if you've gotta err.

 

Here's the big bungle.
I tried to get the timing cover on - should have done a dry run first. Got everything all clean and gooped in silicone and just couldn't get the crank keyway aligned. After so long trying I put the crank pulley bolt back in and just kept spinning it til I got lucky, but at that point maybe 30-40 minutes had passed and the silicone had skinned, rubbed on the chain, it was a fiasco.

Couldn't tell if the o-rings stayed in place through all the fuss either, so I yanked it back off to verify thinking everything was aligned and should slip right back together. I don't know how it's possible, but it wasn't so. I'm soaked through my socks in sweat, so I'll just have to try again tomorrow (after cleaning and re-prepping)

Here's some shots I took along the way.

Water pump - New gasket plus silicone because I didn't feel comfy just having a coated metal gasket when the surfaces looked somewhat pitted.







Then the oil pump. Cleaned and packed with vaseline as per the manual. Note the little triangles on the pump gears - you're supposed to be facing you when you reassemble. Orientation of 'em only matters for getting them aligned on the crank.



Water bypass pipe gasket


And all the silicone I'll have to scrape off tomorrow.




Plus extra for block seams

 

Sorry it didn't work out...

I only liked that post because you are doing a great job documenting this for future members.

Tomorrow will be a better day.

 

Man, it's nice having support.

Slammed busy yesterday, but today I got the mating surfaces re-cleaned as well as the o-rings to the best of my ability. I'm doing dry fits presently and it's just baffling. I get it seated, take it off, cant re-seat it reliably. This time I'm reaching my phone down in there and snapping pictures of how the crank fits into the inner oil pump gear. That's the problem, and I'm determined to get a better understanding of it before risking another 2.5 hours of cleaning and half a $15 tube of silicone.

I'll post up with pics as soon as I have success.

Oh, and this time I'm keeping a fan blowing on high right next to me. Turning the crank a milimeter at a time while wiggling the timing cover is sweaty work.

 

^^^this^^^
I have used MMO to fix dirty hydraulic lifters that wouldn't pump up and were clicking over the years. One pint added at an oil change would usually quiet the "tick-tick-tick" within a hundred miles or so. I learned this from my Dad who did this on his 1950's to 1970's cars when the oils back then were awful. Cars would get lifter click even if you changed your oil frequently. Ford 289's were a very good motor back in the day and legendary, (father of the 302) but they tended to burn oil as they got older and the lifters would clog and start clicking. They would usually quiet down fairly quickly once they pumped back up after initial start, but it was nerve-racking to hear. MMO cured this easily and none of his cars were ever harmed from using MMO as a remedy/cleaner. It's basically transmission fluid.

Side note: I recently had to add a quart of fluid to the transmission in my GM antique (1950's): $10/per quart for the old(est) school "flavor" of Dexron/Mercon fluid. Think about that: $40/gal for transmission fluid.

Pick one:

 

If you need a tube of toyo seal packing 103 FIPG Ill send it to you .

 

@Williston I'll surely keep it in mind after I get this darned thing assembled!

@Dacapster I bought two tubes of Hondabond HT a few weeks before starting this job - only intended to use 1. I've never tried Toyota's, do you like it?
My love affair with Hondabond began when I attempted a carb swap on my XR650L. Switching from the stock vacuum CV carb to the infamous Keihin (mother) FCR pumper carb. Some Canadian gentlemen made it sound easy.. I'll never get those two years of my life back, nor will my bike. Anyways, I had to use an adapter to fit the air boot to the carb, and during tuning (2 years) it regularly saw backflow of fuel. Hondabond was the only silicone I tried that could endure it. Fuel would still soften it, but it'd resolidify and keep the seal. That holds little relevance for this job, but it's the only one I've used since.

Now for the timing cover. Here's the deal: I'm an idiot. Pure and simple. I confused the key on the crankshaft with the needless keyways in the inner oil pump gear. Kept trying to line the two up, but it was the flats that I was supposed to align...

Here you'll see the key on the crank. and the (to my knowledge) stupid, useless keyways in the oil pump gear. Whatever. This is how it fits.


I kept focusing on the wrong thing, and in doing so I'd readily forget about the hard plastic water bypass hose and how you have to align it too while affixing the timing cover. I psyched myself out.

But we're back on track. The timing cover is mounted and torqued where possible. The haynes manual DOES NOT accurately display all the fasteners that you need to install, and incorrectly instructs with regard to the order of installation for one bolt (hidden behind the ac compressor bracket that it tells you to install first). It also doesnt mention the 4 bolts that connect to the underside of the timing cover. Or two bolts that go in the backside above and below where the water bypass hose attaches.

No big deal if you're calm, cool, and collected.

Anyways, the mystery is solved for me. I'm beat and I need a shower. More work tomorrow, along with more details about today.

Here's a little bonus though. My mother was off work today and helped me get the bolts around the bypass hose tightened up. The picture makes it look like daytime. Wasn't. She helped me out through sunset and into the dark as we both tried to avoid cursing in front of each other.

 

Glad to see you are back on track and making progress. I don't envy you working outside in FL this time of year. I did a head gasket job on my 2008 4.0 V6 during the winter in the Chicagoland area. It was cold but I had a garage to work in and I was able to use a propane heater on the coldest of days.

 

seemed to work well when I did cam gear flip mod.

 

Re: Your Mom helping out: Be nice to that woman: you'll miss her when she's gone..... Trust me: Mine helped me drop the transmission one time in my 1993 Volvo 245.

Thanks Ma! RIP

 

Very much concur and heres a 2nd toast to your Mom for helping out!

Process is moving along though.

 

Things were going well and I was sure I'd be buttoning up today, but, well, that isn't what happened. I'm now in Kentucky, headed for Detroit. An impromptu trip to see family.

I expect the trip to take 5-6 days. I suppose I won't have anything for yuh 'til then. Unless you want pictures unrelated to the Taco.

Hopefully we'll get to stop at a few more cool places.

Hopefully I can remember where I left off.. Last I checked there was a mystery bolt and a missing oil drain plug

 

Post 'em up!
We like road trip photos.
