Just changed my timing chain on my 22re 4runner. When tightening the hidden head to timing chain cover bolt, I cracked the timing chain cover. I suspect that it is because of the gap between the cover and head. Does anyone use anything other than RTV to seal this? I think I am going to make a gasket out of gasket material to take up the gap. I hope I don't crack my new timing chain cover.

I wonder if you got the correct timing cover. 84 and older covers are different from the 85 and newer. Never run into cracking a cover. Seems like I have heard of people stripping the bolt hole out from over tightening.

It is possible the OP broke the cover from using to long of a bolt bottomed out and kept going .

There should not be a gap there if these is something is wrong

Most times it is the other way around having the head milled or block decked then the cover is to high.

Gap? I did not have a gap.
Do you have any pics?


I did bust a bolt head off. But i said screw it and put washers under the ac bracket to put pressure on that spot. 75 miles so far and about 1/2 tanks idling. So fat no leaks that I can tell.

I used Ultra Gray for the whole job.
I already had the head on and torqued down. So it was a choice between leaving it or choosing my leak spot the head or the bolt. So far no leaks.

The gap is what has me thinking there could be the wrong cover on it.
