Yotarobs 4runner build

What do you mean by dry? I put a little oil in the cylinder throught the spark plug hole to see if it helped the compression & got no change. In hide sight I think I should have warmed the engine up first to get the rings to expand a little & get good oil everywhere. I am thinking about buyin a leak down tester from Harbor freight & see what happens.

At this point I could prob. swing buying a new head for it, but rebuilding the short block is not in my budget

 

if you put oil in the cylinder, then it is Wet and should have been significantly higher..?? 140+ i think. how many miles are on the engine?

 

186K on the odo. I am thinking that I am an idiot for not warming the engine up, it was 35 deg. for crying out loud. I put about a cap full of oil in the cylinder & it made no difference. Is a cap full enough? I don't see how it could have gotten all the way around the ring to help seal it. Also I only put the oil in the first cylinder, when it made no change I didn't bother with the rest.

LOL, I am still optamistic that it is going to be fine. We'll see.

 

LOL.. i just now got the pic.. funny. Seems like you could just replace the rings and be fine.. i dunno.. never worked with that engine. You added oil and there was no change??? that doesn't sound right at all.. sounds like a fun project alright!

 

I have half a mind to just leave it the hell alone & get it running the best I can like it is untill more fundage becomes avaliable. I still say that if the engine was warm I would have gotten much bettter numbers. I think I am going to repeat the test tonight & see what happens. How much oil am I supposed to be putting in the cylinder? If there is no change then that means that the rings are fine & I am loosing compression throught the valves right? I don't think it is the head gasket because the numbers are so even.

 

Does anyone have access to a leak down tester?

 

Adjust those valves and do the compression test again. With the intake off could you see if there was a bunch of crud/carbon stuck to the valves?

 

I think that I have one Robby, let me look in my Box tonight. Yes, I am thinking valves now too... focus on the head, and try adjusting the valves and replace the timing chain as planned. This is probably a better thread for TTORA sadly than TW..

 

Thanks Sam, let me know if you have one. I did find one at Harbor Freight for $40, might be a good investment. I am hoping the head is the problem, i can just buy a new one from engbldr.com with an RV cam for under $500 or possiblly have mine rebuilt. I have another thread going on yotatech.com but those guys are not so easy to get info from. They get pissed off if you ask questions & just tell you to search, search, search . I am tired of searching, isn't the point of the forum to ask questions & get ansewers? . Thanks for all the input guys.

 

LOL, let me know if the assholes are willing to loan it out for an evening. I might try to rent one.

 

as I recall, I think mine is a cheap-o from Autozone.. you are welcome to use as long as needed. I haven't used it in years.. well.. since I bought a Toyota..

 

you sure do know a lot of assholes..

 

lol thats terrible same

 

is that you on that thing?

 

nice idea, but I don't think so .

More I think about it, It would be cool just to get this one running the best I can & buy another engine & slowly rebuild it.

 

Don't count me out yet!

 

LMAO, yeah I'm sure you are right about the angry squirels!

 

Thanks a bunch dude, I will come get all that stuff out of your way ASAP.

 

I spent several hours tinkering with the cream puff last night trying to get it running better & hopefully getting it warmed up & repeating the compression test. I started by removing the valve cover & adjusting all of the valves. Every valve was set too loose, some as much as .008" others where at least .003". The valve adjustment was easy! When I was putting the valve cover back on I noticed that a few vacuum lines to the EGR valve didn't seem quite right so I found a diagram & ended up re-running a few of them, I must have had a pretty bad vacuum leak. I already had a new distributor cap & rotor so I went ahead & replaced them, the old cap was badly corroded! After that I couldn't get the plug wires to stay tight on the new cap? The prevous owner had replaced the plugs & wires already & he gave me all of his recipts so I decide to go get the wires warrantied at Auto Zone. I also picked up a cheap set of spark plugs. It had a nice new set of E3's in it but I think I fouled them out turning it over . I am going to clean them up & reuse them later. The plug wires fit much better! I tried to start it one more time & she ran great!!!! Nice & smooth, no spitting or sputtering, just like a top. I was so happy that I didn't want to ruin my good mood by doing another compression test so I am saving that for today! It is still leaknig oil pretty bad, I am going to try to get the timing chain done and work on the exhaust leak this weekend.
