  • It just keeps getting better (and more expensive)

    So yesterday I started to the car out to go to the local Saturday morning cruise/meet, Donut Derelicts for those who know the local SoCal tradition. And the motor made this little tack-tack sound which got louder over the warm up in the garage.

    Being suspicious of valve train noises I pulled the valve covers and checked the lash. Low and behold the number 5 intake had opened up by .100+ and the rocker looked good, the adjuster was solid and and the valve was at the same height as the others. Checking the filter showed a few little hard metal chunks. Pulling the manifold revealed a roller lifter that had not been rotating all the time and some MIA needle bearings as the lifter body had contacted the lobe. The roller still spun but was back into the lifter body and would hang up a bit as I moved it with my finger.

    Looks like more investigation is in order, but these were three year old lifters and that seems to be just a bit too long. So add a new cam, lifters and springs to the shopping list. I'd figured to do this this Summer anyway but I hope nothing else got scarfed up. Gotta love the Drag Week addiction, it keeps business going for our friends in the aftermarket. Maybe it'll even go a little faster?

        It kills me we can do some amazing technological things but can't seem to make a solid roller lifter that is 100% dead nuts reliable....

        Good luck with it Bill!

          These are (were?) Crane Ultra-Pros and honestly I think I got more than my money's worth given the .800 lift, 1:8 rockers and the number of passes and the amount of street miles. I'm about 95% convinced that I'll go with the Isky easy roll solid bushing style for the next set due to my perception that there is a lesser chance of collateral damage if there is an issue.

          The big question is spending the money to have the lifter bores bushed for larger lifers and their bigger wider rollers. .904 or .937, the 1 inch stuff is crazy expensive.

            They all go bad. LOL The ones that don't, have a mild lobe and a Hydraulic Roller. Bill has the right perspective, Solid rollers are race only and if he got 9000/12000 passes out of them, they where used up.

              better in driveway than driving

              Sucks that it happened at all but at least it was in your driveway and not on the road. A dropped or misguided valve could have caused a bunch more work and expense. I am finally learning that the valve train is often the hardest working component set so looking only at price, which I often wind up doing, can be detrimental. I haven't gone to your level Bill and Jeff but I certainly spent more coin than I originally wanted to for some peace of mind.

                the valve train parts are consumables essentially especially in a Drag Week style context. Given what might have been I'm lucky as it was a last minute decision to take my truck on the CC Anti Tour instead of the car. Could easily have happened at freeway speeds 150 miles from home. Now for the 'as long as I'm doing this I might as well do that" part.

                        I have buddy who just recently set a single pot 125 CC Bike record at Bonneville. He has similar kinda wall of decorations and few tribute photos.

                        My deal has improved a bit the cylinder walls are pristine and the cam lobe looks like it can buffed out as it has just few tiny scratches. So now onto the replacement parts and inevitable upgrades "as long as its apart..."

                            So, will a tunnel ram equipped EFI motor work equally well with a single 2200 CFM TB as it does with dual 1180 CFM TB's?
