Lucien Frederick - Cam Failure #841

Date 8/19/07


Oh, could be de famous "Angle Valves"

http://www.v8sho.com/SHO/FordHasaBetterIdea.htm

That will effectively shorten a valve?

thou shall be dubbed #841

Tim, hard to say exactly what the issue is without a full teardown. It is a front head refurbishment following a cam failure. Don't know if it is the original or a replacement head. We know that it would be the intakes that get bent. This head has five intake and four exhaust valves out of spec and all have excessive gap. Oh by the way, I didn't see a failure number assigned. Failure was in the fall of '03 at about 92.8k miles. #1 plug came out at 112k miles just over 2 years ago. Has been sitting since then. VIN is 1FALP54N7TA254109.

I am sure you are correct, lately many things I figure out for my self are 100% wrong. ;-)

I still wonder if it is not a clue to some underlying valve geometry issue?

The infamous valve stem shrink?

Could all the valves be ground incorrectly?

eccentric CAM bearings wear?

yes, eureka!

not too often a push rod or rocker arm issue with our cars?

Tim, that would give me a tighter clearance as the valve stem tip would move closer to the cam. Lucien

I wonder if someone rebuilt the heads and sunk the valve seats too deep?

Yeah, PP job refurbing. It's as if they installed new valves, seats, and ground the stem tips. Obviously no time spent on dry fit up to use the thinner shims. These are the largest ones I need. Got 4 thinner ones coming from a vendor. Checked the local Yamaha dealer and all he had was a new style about 1/4 " in diameter. Said the larger diameter ones are from an older design. Someone thought Kawasaki also used them. Couldn't locate a Volvo dealership open this afternoon. I will try calling around Monday to see what is produced for their 4.4L. Maybe a source for ours.

Holy Crap Lucien! - Those are more like sewer caps than common V8 SHO Shims.

Can't you just stack 2 or 3? ;-)

Lemme dig though the pile and get back to you.
FWIW, Yamaha dealers can get the shims, you might have the best luck
with them on super thick stuff like this.
