Where’s your comfort level?

Made some progress but had enough for today. Have to get up in the morning and play “ where did that 3”Phillips screwdriver fall?” Image Unavailable, Please Login Image Unavailable, Please Login

 

sounds good. Thank you!

 

85 Euro Quattrovalvole. What are these little guards ( sitting on the 2x4 blocks) Image Unavailable, Please Login Image Unavailable, Please Login supposed to accomplish/deter? My car doesn’t have the back Covers that go behind the belts/cam pulleys to keep unwanted items from trashing the belts.

 

Okay, that makes sense. Had no idea why they would have two sharp little angled pointers on them. Thanks.

 

Image Unavailable, Please Login Ran into an issue this evening..
Found TDC on flywheel but I only have timing marks lining up on one cam. It’s on the front bank closest to the Plenum, (intake?) The lower cam looks like it’s about a tooth off. Rear bank cams are both equal but are 1/4” off the index mark. An abstract black paint Mark coinciding with this on the cam gear for that rear bank leads me to believe that this was done last belt change or earlier. I’m positive belt hasn’t slipped. tensioner looks good and the belt tension looks good. Cam cover gaskets were of a black material and orange ATV sealant was used in places around the cam o-rings but none of it look like it sealed I mention this because I’m wondering if The last person to perform this had less experience then even myself. Let’s not forget the missing water pump alignment dowel that allowed the pump impeller to chew the hell out of the pump housing. Anyway, looking for some advice . I can see the front bank exhaust cam being off one tooth pretty easy if you’re not careful, but (knock on wood) how can I be almost a 1/4” off on marks lining up for the rear cams and not have valves colliding with cylinders? Given all these index marks are factory would I be OK removing the rear cam belt and rolling both those cams back so they line up? Making sure that each cam only moves that 1/4”? Then do the same for the front bank where that exhaust cam is off one tooth. Really don’t want to start removing cams as I’m not comfortable with that at all.

Well I’m glad to hear that. Starts easy and sounds good (to me). Had visions of now needing to borrow an enclosed trailer and take this to Spokane for repair. Still bothers me immensely that these marks don’t line up.

 

Good morning. Yeah, degree wheels and pulling cans are above my Pay grade. Probably wouldn’t be so intimidated by it if I would just study up on it.

A little history on my 308. It was originally shipped to Saudi Arabia and accumulated around 10,000 miles on the odometer. Was then purchased and imported into the United States where the next owner put 2000 or 3000 miles on it and it developed a major motor issue. Was brought to Tim Holt/Holt Motorsport in Indiana, he employed 3 Ferrari factory train mechanics that rebuilt the engine top to bottom. I spoke with Tim the same year I purchased the car and he called me another couple times after that. Reason I bring this up is that the car had maybe 13,000 miles on it when this happened. He said the Saudi‘s are notorious for not checking the oil and that’s what happened to my car. Odometer now shows 40,370 miles so it has less then 35,000 miles on a total engine rebuild. So I guess now the question is.. do I take those factory marks as assembly only? And that the discrepancy was done fine-tuning by the Ferrari mechanics OR is this the product of some nose picker holding a wrench in one hand and a tuna fish sandwich in the other and not paying attention? What to do, what to do this morning besides drink coffee.

 

Going through the service records that I have on the car..
1992 in Reston Va. - belt/bearing/water pump replacement. Odo. 24,672

1995 in Reston Va. -belt/bearing/water pump replacement. Odo. 29,298

2011 in Jacksonville Fl. - belt/ bearing/ water pump replacement. Odo. 39,300

So with this, it’s had three belt/bearing services since being rebuilt. Leads me to believe the discrepancy in timing marks has more to do with not being careful. Nothing to confirm this however.

 

Yes, I found it’s a little bewildering myself this morning.

 

I remember asking Tim Holt if he had any repair invoices for the rebuild. He looked for me but they were long gone by that time as they had moved to a different state? IIRC The repair bill was just shy of $20,000 so I’m sure if any parts were needed they were all brand new and not salvaged.

 

good morning! Yes, this was not the case with my AC compressor could absolutely not get it out without hitting the fuel tank. Ended up disassembling all the brackets/ Compressor to get it removed. Added about 2 1/2 hours to the project. Included me shortening the studs and grinding some of the aluminum out of the mounting bracket so the belt had more clearance.Next time should be a breeze. Was void of R-12 and really don’t think I will reinstall it,just put it in a box in the shop. Never use it any way.

 

So I’ve just spent the last four hours reading archived threads on degree wheels and setting Cam timing. Two observations..
- It’s going to take a loooong Time for me to understand and use a degree wheel.
-I was surprised that some Ferrari technicians and professional mechanics that post here ,(won’t name names) stated that after using degree wheels and other aspects of Cam timing procedures, that once said and done the factory timing marks on a 308 engine were extremely close to right on, maybe 1/2 degree + or - and unless you’re setting up timing for a race car (paraphrasing here ) it was wasted effort.
So..
Am I Okay with realigning these camshaft marks? And exactly how do I go about doing this? OR, do I start making preparation of transporting this vehicle to Spokane Washington which is 250 miles away to someone knowledgeable. OR find a Ferrari technician that wants to visit Glacier National Park in the fall with compensation and complementary suburban included
