for the record, I took them out individually, one at a time, and put them all back in their respective slot.

Not possible...the systems are not linked at all. One less thing to worry about. Maybe this is possible in some systems, but no Volvo's. Your store manager apparently knows very little about our cars. The only part of the brake system linked to suction to the engine is the servo and that contains no fluid what so ever.

I would estimate they moved back and forth around .100-.200 inch. easily.

I really hope you meant 0.010 to 0.020 - 1/8" slop in the lifters is a really bad thing and even 20 thousands seems excessive. I looked in my books and I can't find a spec for the play. If you have 0.020 slop in the lifters it may well cause the tick you describe.

Did you try swapping the lifters out, for testing purposes, to the holes that had slop?

Lifters are a heck of a lot harder than the aluminum head so my guess is that if you have excessive wear it is on the head side and not the lifters.

By virtue of the fact that you posted your observations, I think you know what you need to do if the lifter holes are worn out.

Ozark, I believe we have some confusion about the play with my lifters. I was not referring to the play in the lifter holes, I was reffering to the play on the inside of the lifter, the part that sets against the top of the valve stem. I could move it up and down a great distance, very easily.

There is absolutely no play in the holes where the lifters sit. Just on where they make contact with the valve stem.

I suppose the easiest way to explain it, was that I was only able to collapse those two lifters. VERY easily. When I tried on the other lifters they seeped oil out or sucked oil in. These were as loose as a rubber diaphram. They had a lot of play.

Any Ideas?

Great - I did think that you had that much play - laterally - on the holes. Thank God that is not the case.

The lifters are hydraulic and they need their charge of oil to work properly. Do you have a blocked oil passage to the top of the #2 cylinder? It sounds like you just have the upper cam cover off of the car. As you know, you need the liquid gasket goop to seal it back up, but try soaking the lifters in a pot of oil and see what the lash is like after that - they kind'a self charge if they are good.

Ok, a month later, replaced all 20 lifters, and head gasket. put the car back together cranked it up and it was whining really loud and smoke started coming off the back camshaft. Its as if this problem is never ending.

any advice?

ok the smoke looks as though it is coming from the back cam sprocket. Any ideas?

Back cam seal may have dried and gone bad...you can pull it out and replace it or pull it out, clean it really good and then use RTV around it and push it back in...it should line up flush to the opening- not all the way in. Good luck and let us know how things go.

I replaced all the cam seals, Do you really think it is something as simple as a cam seal put in wrong?
