Hey guys, I ended up buying a junkyard motor and tearing it apart. Head gasket looked like it was gonna spew... We took my ported head off my old motor and planned on putting it on the new junkyard block after noticing a tranny bolt hole on the block was busted. We put new Clevite 77 rod bearings in and left the internals stock... we also put a higher volume oil pump in there. We took the timing cover off found a double roller timing chain and decided to swap it for my newer one... after we had the head off we pulled the lifters out and seen that the motor was fully rollered motor.... Is that normal for the 2.2 OHV motors? Thats my main question for now... it was a good thing we checked though because a lifter broke and bit into the cam grinding a lobe down... good thing I had a whole other motor.

Wait, double-roller chain on a roller cam motor?




fortune cookie say: better a delay than a disaster

That don't seem right. All the assemblies in this engine family came with Timkin-link chains after '82, and the roller-cam wasn't installed 'til '94! Dude, either you got someone's old build-up engine, or some wrench went through the bother of installing the '82-only timing set. Answer me this: Does the roller chain set tensioner also have hold-down by a stud or bolt for one of the crank main bearing caps?

Go beyond the "bolt-on".

Let me be more specific, it is a 95' motor so what you said about having roller lifters after 94' should be right. I just went through the motor for the first time and didn't know if a 95' motor was supposed to have any rollers in the motor.... and is it still considered a LN2? I got confused when I went through the motor after reading about them on these forums.

How about posting up a pic of that timing setup.....

'94-ups had the hydra-rollers in them. And yes, all OHV 2.2Ls (From '90-up) are considered LN2s, except for the flex-fuel versions which are known as L43s. But they're still all the same engine with only minor variances in details every so often. Still, what you have for a timing chain setup is not factory for your app.

Go beyond the "bolt-on".

If the chain is wrapped around the gear and you are looking at the "side" of the gear rather than the flat face, here's what you should see:

Double roller chain, there will be two rows of links side by side and you'll see the tips of each gear tooth showing through each link.
Single roller chain, same as double roller except only one row of links.
Silent chain, no teeth visible through chain links.
