Engine advise

So here is what happened in short.

Went to get my 37’s off the truck to groove them. Started it up and was running fine then all of a sudden tack, tack, tack, tack. Sounded like a lifter or somting in the valve train. Didn’t run it much. Got her on the tailer and off. The past week got it to the shop to diagnose valve train noise but couldn’t find it. So I started to tear her down untill I found the problem.

Found a small metal ring in # 1 cylinder. Cant find where it came from or what it came from. Best guess is it got into my intake system the many times I have had it off. No major damage to piston, cylinder wall or head. Just enough material to make a slap between the top of the cylinder and head, vert lucky I know.

4 years ago I overhualed my 2.9, new loaded heads, pistons, all bearings and such. Only thing I didn’t do was the cam bearings, cam and lifters.
So im in a delema of what to do now that I have it torn down. It ran great before I tore it down aside from the tick from the ring in the cylinder. Although It had same lifter tick at start up and when revving the piss out of here. Cam bearings will solve upper end oiling thus the older 2.9 upper end noise. I want to keep the 2.9, DON’T SAY ENGINE SWAP!!!!!!!!!!!!!!!!!!

This is what I have been thinking. Least to most expensive.

1, Just new head bolts and head gasket kit and put her together.
2, New head bolts, new cam bearings and gasket kit.
3, New head bolts, new cam bearings, lifters and gasket kit.
4, New head bolts, new cam bearings, cam, lifters and gasket kit.

Im leaning tward #3 the most. Can I run new lifter on an old cam? Still have to brake the new lifter into the cam?

Let me know what you think.

ENGINE SWAP!


If you replace the cam would you go for a new stock style or aftermarket? I'm leaning towards at least 4, just so everything is fresh in there.

I would lean more towards #3, maybe #4, depending on how the cam looks. ARP bolts maybe?

The cam lobes look good.

If I did go with a cam I would like to go to somthing for better low end. But then I would have to mod to MAF from air density for any benifits. And I really dont feel like doing that at this time.

ARP bolts? Brand name?

2.9 head bolts are tourqe to yield, thus they must be replaced each time.

Indeed they are, just throwing it out there...

 

[Todd]

so whats the deal with ARP bolts? Are they a brand name with some advantage over others?

No. There's no point to them on your motor.

I don't think the cam bearings need replaced. There's not much load on it and they shouldn't wear. Mike it though before you do it. Cam bearings are a bastard. I would take the lifters apart and clean them. Just put it back together. If it's out, I would mike the crank.
