cam failure

[86george]

Yes another flat tappet cam gone bad.Bit of a chore getting the pan off with 4 billet caps but i got off.Looks like some thrust bearing wear.The engine will come out so i can check the rest.The oil pick up screen had a lot of filter material on it.Been useing wix 51049 filters since i got the tubo saver. Thats what came with the saver kit.Used purolator filters before that.One or both of those filters suck.Used shell rottela oil for a couple of years and been useing zddp for over 3 yrs.Damage must have started before i started useing the zddp.I'm thinking roller kit this time.I don't plan on going any faster than mid 11's (no roll bar) so what are some good choices for a roller cam?

I haven't gotten to the track yet but my 210/215 feels good on the street.

X2 I had 1 pass where I spun till 1/3 track & still ran a mid 11. That was 1st pass on new combo without any real tuning. Just the stock settings on my TT chip. In the city it responds well with good vacuum for my brakes.

I could do a search but what are the signs of a cam lobe going south becides material in the oil or pulling the valve covers and taking a look?

Mine started pecking noise like a bad lifter.Changed oil to thicker oil and noise came back.Noise came up though the intake.Hard to tell where the noise was comeing from.Not like a single lobe or lifter.Ran the engine with valve covers off and found a couple valves opening and closeing very abruptly.Had a cam fail once shortly after break in.Single lobe failed and that was easy to find.

If you run a magnet on the drain plug, and you wipe a lobe it will look like a freaky fuzzy mess, and then your blood pressure goes up... and your wallet gets thinner.
