Just wanted to post some pics of my little project i got going on here. 1987 Toyota 4Runner, over 300k miles..replacing timing chain, both gears, tentioner, oil pump and all gaskets..FUN FUN!

 

In that last pic... It looks WELL within limits...

 

Exactly what i was thinking! haha

 

Its not that bad is it?

I got your PM, I have attached a PDF of the instructions. Keep in mind the instructions say to warm up the engine, but the lash adjustment specs are given as cold specs. I adjusted mine cold, and it is fine.

You want to make sure the feeler gauge slides without any binding. It is better to deal with a little noise then to tighten the valve too tight. With the valves too tight it can cause a misfire, and also cause an exhaust valve to burn up, since it cannot sit against the head to dissipate the heat.

Good job on the chain, keep us posted.

 

Okay thanks a lot for the pdf file on how to adjust the valves i really appreciate it. Im just waiting on my parts now..then its the reassembly process. I havent taken any of the timing components off yet. Just have the engine at tdc, valve cover off, oil pump off and timing cover off. Also removed the oil pan to clean out the broken chain guide..its been fun so far just hope i can get it back together with no issues! Thanks for the help again.

 

Timing chain job is complete and was a success! New chain, new cam sprocket, new crank sprocket, new guides (steel backed driver side), new tensioner, new milling oil pump, new oil pan seal, valve cover seal, timing cover seals, water pump seal.

Runs like a top and no more timing chain slapping! Now all thats left to do is adjust the timing to 5 degrees. Im 22 years old and have never done a job this big..feels good to be successful! 297k miles and still tickin...
