Lifter issue with an XY 250 - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Hey guys, I was wondering if anyone had heard of two different size lifters that are used in the old 250 2V. Was just putting the new engine together on the weekend, got a set of lifters for it, and after alot of issues in getting the timing right we smacked a lifter out of the old block to discover that the old lifter is bout 4 mm shorter than the one I got from repco. I even confirmed the product number with peps aswell and they have that exact same longer lifter for the 250. It took alot of hunting around to even find a possible product code for the right lifter which they have to order in..... Has anyone else heard of this shorter lifter???

Hi,
This doesnt answer your question exactly, but I have encountered something similar..

When I was trying to get a set of roller rockers, it turns out I have to run V8 Cleveland lifters in my 6 cylinder block.

Maybe what you have happening is that one set is the "six" length, the other is the "cleveland" length and they just put the wrong ones in the wrong box?

Is it possible one set are hydraulic, while the other ones are solid etc?

I have also noticed with my three six cylinder engines lying around in the shed, I have two different push rod lengths..

Repco said that the lifter they supplied me are the same ones they use in all ford 6 and 8 cylinder engines from like 1968 till 80's...... It came in 3 box's of 4 lifters, all same with same product code. Peps also had the longer lifter for the 250...... strange

How's this for a suggestion:
I'll measure the lifters I have in the shed (Crane lifters) tonight and report back here tomorrow on the length.
I also have 3 other six engines lying around so Ill measure those lifters too...
hope that helps..

BTW, what is Peps?

Thanks heaps, will be intresting.

lol, peps is a place just like repco up in Sydney, was sure if it were anywhere else yet.

mate the external size of the lifter may be differnt. But the internal size is what matters

Don't mean to start an argument but not according to what some mechanics have told me.......

Are you 100% sure???? Because with a shorter lifter the push rod wouldn't be pushing the valve into the cylinder when it should be shut.... But why would they make the external size bigger without increasing the internal size... any reasons you can think of????

The push rod doesnt push on the out side of the lifter does it.... It pushes on the center of the lifter which is the hydralic part.. THe actuall lifter may be 3 inches long, but if the internal height from the base (flat surface) of the lifter to the internal part of the lifter where the push rod sits is the same as the orignal lifter then there is no problem then.
Im pretty sure youre not fowling what im saying

Simpy measure it ...

The internal part of the lifter is recest the same distance on both lifters. Is that what you mean? With the longer lifter, the pushrod would sit higher, and thus opening the valve when should be closed? True?
