Cam change under way...

Just started today after discovering my wiped cam lobe.

Guess which lifter is good and which is bad?

Great picture. Can you tell us what the cam was and how old?

It was a Comp Cams XE274 which was about 5 years old. I think it had maybe 10k miles on it?

I think it was my fault though. I let it get low on oil once without noticing, due to a leak from the rear of the intake manifold. I won't let that happen again!

If the oil fikter bypass was not plugged there is a very good chance that you had debris go though the bearings.

In a situation like this a plugged bypass and good filter is your best friend.

They're both junk. The left one because it's damaged. The right one because what are you going to use it for, a paperweight? Every cam manufacturer warns NOT to marry used lifters with a new cam. So these two plus the remaining 14 lifters can be recycled and shipped to china so they can melt them into new lifters.

I would drop the pan and pull a few rod and main bearing caps off while you are at it to check the condition of the bearings. I would guess they are all shot. Been there- Done that...

I agree ..... we just are in the final clean up of our newer engine due to a flat cam ... we found junk in both rod and crank bearings ..... would also check your cylinder walls as well .... we did wall hone, polished the crank and had the heads cleaned up as well ...
new cam definately means new lifters ....
sorry to hear this is necessary as it's a real pain in the butt .... and good luck with your cleanup ....

I have new lifters and the new XE274 ready to go in. What's involved in pulling the rod and main bearing caps? Can you do it with the engine in the car? I'm familiar with the top part of the engine and working on it, below the block I'm a bit of a noob and I have no good way to pull the engine.

Not sure about the rod bearings.

You near the golf course in TT?

Yep, just pull the steering out of the way. I had to also drill out the broken bolt while the engine was in the car. I used a trash bag to mask off the engine internals. It worked.

Probably the greatest problem with R&R-ing bearing caps while under the engine is getting enough clearance for your torque wrench. Using a long extension is a NO NO.

I haven't had time to work on it more yet, but I'm hoping maybe the filter bypass was plugged by the PO. The engine was rebuilt about 9 years ago by a circle track engine builder, maybe I got lucky and he plugged it. Is there any way to look at the filter area with the filter on/off and see if it was plugged?

Thanks guys for all the help btw. CF always a great place to vent my car troubles
