There's the Italian Concours D'Elegence at pier 62/63 on September 2nd. I HOPE to make it to that event (was there last year. Great weather, great gathering). | ||

Peter, looking at you and your pictures makes me realize how incompetent I am when it comes to mechanical issues. I'm impressed with your abilities and desires. Me, I have to pay someone to do my repairs (and I'm sure my 30K service just paid for at least a semester of college for my mechanic's kid). I'm also blown away when I see pictures of all the intricate moving parts to a car's motor and transmission. How in the hell do they NOT break down more often? Good job Peter. Hurry up and finish so you can drive down to Seattle and show it off! | ||

Larry Dunn who posts here occasionally has a GT4 like mine and his engine is in the same state as mine is. His bearings too are grumbling and he'll replace as well. Oh man, tell me about the interference fit! I had a problem with everything, removing the ring-nuts, removing the pulley from the shaft, etc... I dressed the edges of the woodruff-key slot with jeweler's rouge and a little bit of lube and the f---ing thing was still tight going on. Its on there now and I don't intend to ever take this thing apart again. | ||

Peter, good to see your picx and your progress. I�m glad you caught your deteriorating timing sprocket bearing. The imminent failure of one of mine is why I took my engine apart. The cage had broken and the balls were deteriorating. While mine is a high mileage car, an SKS rep. to Ferrari told me they�ve seen the same problem in the racing engines -- due to vibration. I�m using an upgraded version of the bearing that the SKS rep. recommended (not a Ferrari listed part #), but it requires some custom fitting on the shaft. You probably noticed that the interference fit on the shaft is way to tight. --Tim | ||

Peter, the story about the O ring reminds me of the Olds Engine Cadillac used in there sevilles from 76 thru 79. They bored one lifter hole oversized on the earlier engines. Naturally that one sleeve takes a different size lifter. They made the mistake, you catch it. Congrats on the work you're doing. | ||

So far I've gotten the transaxle back on the engine (or should that be the other way around?), Anyways, no problems there, pretty straight forward. The front cover contains the oil pump and gear drive for the cam belts. Those seals were ROCK-HARD. This piece was covered entirely in grime. Those bearings were also grumbling (SKF 6203/C4QE6), the inner ones get a supply of oil as they are contained in the block, but these are starved as there are only tiny splash holes to deliver oil.  Here I am using my overhead hoist to drop the trans onto the block.  P.S. Herbert: I DIDN'T forget that tiny O-Ring that fits onto that one stud! I figuered out why its there, that stud is drilled right into the oil passageway. I guess Ferrari had oil blow out past it on prototypes, and figured this would correct it. |
