It's been a while since my last posting and I'm back with a problem: during the last run of the season my engine began missfiring and losing power. Found nearly 0 pressure in no 4 cilynder due to a cracked CF21 solid lifter from Kent Cams - in february 2009 I went for their OP264 camshaft together with followers and ran them ~500 km for breaking in and ~100 km in racing conditions (only 2 events due to low budget issues).
I sent to Kent Cams some pics and this story getting this answer:
"Dear Sir,

Thank you for your recent E-mail ,looking at your photos it difficult to be 100% accurate in the reason for failure, however it looks like the follower has suffered some heavy side loading, the reason I say this is because this product it very strong in a compression state, which is it's natural working environment.

If you would like further investigation, please return the part to either the company you bought from, our directly to our company


Best regards,

Wenting further but with my own investigation I found another follower with a loose tap. I strongly believe that it's a manufacture problem, the margin suporting the tap beeing uneven (0,3 mm on one side vs 0,7 on the opposite one) on the cracked one, leading to tilt the cap. What do you think?
I had to cut the broken follower to get the tap out of it.

I can't figure out what it is or where it goes. Any ideas?

I was driving to work, stopped at a light, car running fine, good oil pressure, and temperature normal. When I pulled from the light, it just totally quit, and wouldn't start again - not even a hint that the plugs were firing. After pulling a plug wire or two on the side of the road, it looked as though there was spark from the distributor, and there was fuel getting to the carb - but it still would not fire. I had it towed home, and have been checking things for the last few days. I pulled the electronic ignition, and put the points and condenser back in and cleaned the plugs (they didn't look too bad anyway) and now the car will run, but the #2 and #4 cylinders always miss. Tonight I pulled the plugs and did a compression check. #1 130 psi, #2 30 psi, #3 140 psi, #4 40 psi. Could this be caused by the cam jumping time (the timing chain only has a few thousand miles on it). Unless someone has other ideas, I guess I am going to have to pull the head and see if I have lost a couple of pistons or valves, but why would something like this happen to two cylinders at the same time? Thanks in advance for your help. ]]> 6A Engine Mechanical amishhacker http://www.opelgt.com/forums/6a-engine-mechanical/22767-very-low-compression-2-4-cylinders.html
