Broken crankshaft key leads to tear down and timing service

Awesome!

Might want to check the coolant level in the radiator as well (not hot) since some bubbles might have worked their way out.

 

Been reading along since the first page, glad you got it going again

 

I’m honored to have had such a long thread on the holy site that is tacomaworld

 

Great Job! I hope you enjoy the satisfaction as well as I always have when completing an involved project.

 

It is very satisfying indeed. Glad to be done haha

 

A little breakdown/summary of where I got my parts from for anyone wondering:

-All timing components(chains, tensioners, sprockets, slippers, dampners, crankshaft key) from Toyota dealership approximately $1250
-o rings for underneath timing cover from dealership $20
-aisin water pump from yotashop $125
-oem pulley from partsouq $160
-felpro valve cover set from Amazon $35
-three bond 1207b gasket maker $25 off eBay
-Toyota genuine seal packing 1282b $40 off eBay

other than the parts had to buy some tools and miscellaneous things like a big crescent wrench(to hold camshafts), 10mm hex socket for timing idler pulley bolt, rags, shop towels and brake clean about $100 probably
Edit: had to get new oil and filter as well. x2 for me since I’m gonna be changing my oil and filter again in a couple hundred miles to get any contaminants out. You’ll have to get more power steering fluid and coolant as well unless you reuse it like me

over all expensive project but worth it and for sure worth doing yourself if able. If a mechanic used all those same parts it would be all that money plus probably atleast a grand in labor. It took me about a week or two to diagnosis but once I started tearing down I had it all done in another 2 weeks. I for sure took my time when it came to the timing but if needed this job could be done in a week or less without rushing. Keep in mind I took photos in and described the broken key issue to a “trusted mechanic” my dad has used in the past and he immediately told me I’d need a new crankshaft, that the key wasn’t removable, and said it would cost thousands. Always worth doing your due diligence and not just giving up and listening to the first “opinion” you get.

 

just out of curiosity, what would happen if one didn't use Toyota sealant
and rather any other kind

I understand there's times to use different kinds. PTFE on threads where needed,
-anaerobic sealant I believe only works on super tight gaps, not large gaps

for example, I have lots of other sealants from working on a different brand that is not Toyota, and have used it before on my valve cover gasket job with success.
Though TBH, if the manual says to use something for the truck, there's probably a reason. Would probably play it safe and get whatever it advises.

 

Probably nothing? Most these days are probably advanced enough to not worry too much. But they are designed to deal with various factors like heat, chemicals, cure time, yo momma, expansion, adhesion, etc.

 

Yeah no idea. I feel like it’s worth it if you want the peace of mind like me. Probably more about how you apply it
