Look at the middle cylinders. This was a failure that had been a long time coming, that and some other things I saw lead me to believe someone's been here before, and their skill level was not equal to the job. Don't forget about the chain tensioner. Any time I repair a cooling system, the thermostat gets changed. I will know more once they tear it open on mon. So I will be doing the rest of the top end when they arrive next week.
I did a head gasket on a 22R a long time ago and remember having a hell of a time cleaning the block and head surfaces. I did not do the head bolts because they haven't arrived yet! During the time your turbo will boost the compression ratio is when the air will get pushed through the head gasket into your cooling jackets between the engine block and head's. They also cover many other issues that you may come across through out the ownership of your vehicle. The part holds in gases, oil, and coolant, but also ensures everything is under pressure. Oct 22, 2009 It's a big job if you've never done one before. I was careful to align the camshafts, but when I tried to start it up I got a P0336 code and the engine would shut right down. I was seeing them fail when the vehicles were so new, I could replace the gaskets and not even get dirty.
Logged what year is it? Runs fine, ready for another trip to the Command Center! So, after 239,000 miles, it got a valve job. I thought it was just a fuel supply issue before I checked the engine code. With the head gasket in place, I didn't want to muck up the new gasket with a sloppy move when trying to put the heavy head on by myself, so I put a piece of the cardboard from the gasket box down to keep a buffer between the head and the gasket while I aligned the head. The camshafts are out of time. My exhaust manifold is cracked! Don't give up on the poor thing.
In the process it seems that I should replace the spark plug wires. I apologize for my ignorance, you seem to know what you're doing. This is borne out by the fact that there are no signs of head gasket leakage into the cooling system. Is this a byproduct of using the wrong coolant? Everything on this truck ran great until this happened. I haven't made any decisions, I will find out more once it is taken apart. I would like some info - what do you guys think I should do if they are cracked? No oil usage less than 1 quart between 4000 mile oil changes, no abnormal noises or issues, no head gasket failures either.
Toyota had numerous material and procedure changes concerning head gasket replacement for those engines during the first 5 years of it's service life, trying to get a handle on the failures. Have them replace the valve seals and check valve adjustment if you feel they're competent to do so. And I had another engine sitting in my garage. Additional repairs may be needed after the inspection, which can add several hundred dollars to the repair and are not included in the RepairPal estimate. Aside from the doing some body work and replacing headlights, my knowledge is limited.

I drove for 6 months, about 2000 miles without a timing chain guide on my 87. When I pried the head up, I could clearly see the damage to the head gasket. And that is if there aren't any other problems like cracked heads or whatever else could be a problem. I dont want to go with refurb or resurfaced heads if they are just going to fail in 60k. They should just need a little buffing.
The head will not come off with the belts attached, so I first removed the bolt for the dipstick and then removed the belts by loosening the idler pulley bolt then loosening the tensioner bolt until I could remove the belt. This part is also sometimes called Toyota Tacoma Engine Gaskets. This manual will provide you with all of this information step by step. I have taken really great care of the truck since I got at 68,000. I've haven't removed the camshafts or distributor, but who knows what the previous owners did. I did the same process, very carefully, on the aluminum head, taking care to not remove any aluminum, but only old gasket crap that was stuck to the head. There doesn't seem to be a visual mark on the gear side of the distributor.
Safe to say, engine performance can be severely affected by a blown head gasket, and ignoring the symptoms not that you could can lead to big trouble. The other end is on the intake side. Picture 1: How much has to come off to get to it, and organization is the key to putting it back together. Bill The original gasket failed you, why did use another inferior gasket?? As when you do your head gasket you wil need to remove your timing belt and this is a procedure in it's self. It's hard to tell just how much they peeled off the head when they resurfaced it. Spent a couple of hours on it Wednesday night after work, finished the teardown this morning. I first cleaned the block surface with a flat scraper.
The block was absolutely covered with crud. I doubt they need resurfaced. They just usually move everything right over in hopes it'll be alright. Did you remove the distributor or either camshaft at any point in time? I want to fix it, I don't really have any other choice. That is what I meant. For car owners who place high importance on long lasting service life and technology, Toyota can be counted on.
