ohc engines
Ok a guy I work with swears up and down that his 2.0L DOHC eagle talon has lifters in it even though it's an OHC design. I think he's full of it but I wanted to know if anyone else could verify it.

Well, now.... wait a minute. He may not be all that dumb.
His terminology may only be incorrect as he is probably thinking of the hydraulic valve lash adjusters. The camshaft operates aluminum center-pivot rocker arms that have roller bearing cam followers and miniature hydraulic lash adjusters above the valve tips.
Fords have them, too. Otherwise you'd be setting valve lash every few thousand miles.

Yes, hydraulic lifters with OHC, and DOHC engines are very popular.
Here is a good explaination:

Ok so it's called a lifter sometimes but it shouldn't be confused with a pushrod style engine lifter. That makes a lot of sense, and yes he is that dumb, the conversation started when when another guy at work bought a new cam and lifters for his buick 350, and the not so bright guy looked at the lifters and said that he need those for his talon cause they were ticking.

Sounds like you just want to do a hatchet job on the guy. You got your answer, but you are not pleased by it?
Maybe the guy is just a joker or he's just baiting you.

Some engines don't use the rocker arm arrangement. The Cadillac Northstar, and the GM Quad 4 used a setup where the lobes ran directly on the "lifter" (we called them buckets at my shop) which was placed in between the cam lobe and the valve stem. They were hydraulic tappets, with no provisions for lash adjustment.

I believe Jaguar has used those lifter/buckets between their overhead cams and valves for 50 years or so. If I remember right...to set the lash you have to measure with a feeler gauge and then take em apart and add little shim-discs til it's right. Not a cheap proposition for a shop to do.

The Ford 2.0 used a rocker arm setup where the cam rode on the top of the rocker, one end of the rocker actuated the valve, the other sat on an adjustable pivot. The 2.3 used basically the same setup, except that the pivot end sat on a hydraulic lifter, eliminating the need for adjustment. -TD

I do have to honestly admit that yes I do have something against the guy, which would be a whole other thread of me venting, very long personal story.
I think I know where you are coming from. I have learned the hard way it can take a lot away from your life if you let guys like this get under your skin. It's not easy, but sometimes the best thing is to just let it go....In the end, it's not worth it in the overall scheme of life.
