22r Timing chain

When changing the timing chain on a 87 22r do you have to pull the head off? I'd rather not if I can help it.

No you don't have to, but unless it's done carefully, you will get leaks.

You don't have to--but be VERY carefull and pay close attention to where the timing cover mates to the head..

Ok good. It hasen't been back together to long and I didn't want to pull the stupid head again. Now I wish I had just replaced the stupid chain, guides, and tensioner when it was first apart. Oh well.

i found it really hard to squeeze the headgasket in when trying to fit the timing cover back on, tight fit.

Another question, getting the crank pulley off, which way is it threaded?rh or lh?

you either pull the head or the pan, unless you are a talented mother. to me it's worth the added 20 minutes of work to not chance folding the head gasket.

x2, I have done it without pulling either of them off with no issues afterwards, but usually I do an oil change at the same time, so pulling the pan off and cleaning it out isn't abig deal.

Just don't forget the hidden bolt in the head.

I have done a # without pulling pan/head. Just be very carefull also when you tighten down the hiddin bolt--had one pop the casting on the cover.. Doh.
