I blasted the rear cover, it was a real mess then hit it with the same paint I use on the block and gearbox. Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
The breather tube and elbows at the valve covers had an abrasive in them. Not sure where that came from. Ill be giving the oil tank a close inspection. Image Unavailable, Please Login Image Unavailable, Please Login
Im going to refinish the plenums next and wrap things up with the engine then prepare the engine bay. Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
Image Unavailable, Please Login Lovely work Paul. Good to see. You should make a purpose build trolly stand for the BB engine you do that many of them. I don't know if you remember mine, but it works well. The mount set up is the copy of the chassis and mounts in the car.
Pretty but I don't have the room for things like that and mine works on everything I put on it including a gearbox upside down, 308, boxer, Countach, V8 anything engine on its end etc.
Just wanted to comment on a detail of the 512 (and up) oil fill hole. Note the oval machined boss for the fill plug. When the 365 came out it had a round boss in a lower position (bottom of the oval to be exact). Ferrari came out with a revised insert that went in that fill hole that looked like a tube that curved up so the oil level could be increased without running out of the fill hole. Later ferrari altered the mould to eliminate the curved tube and machined the fill hole in the higher position. Image Unavailable, Please Login
You do the test before the engine goes on the gearbox and if there's a leak you'll see it dripping off the end of the liners.
I thaught so already because otherwise you not can see if dripping so when you not remove the gearbox and make a pressure test you may have a problem later without knowing why. but I think once the liners are tight they will not start some day to drip? or you once had such a problem paul?
Ive had a leak before going on a gearbox and its safe to say it shouldn't leak later if it passed that initial test. I haven't had to take one back out for such a thing and now Im jinxing myself!
? what does this mean? jinxing? can not find in the translator but if you perhaps have the engine out and install for example new headgaskets and new waterpump do you separate then the engine from the gearbox to make the pressure test or keep it together? it is normal for me when you overwhaul the complete engine that you make this test without gearbox.
QUOTE=I blasted the rear cover, it was a real mess then hit it with the same paint I use on the block and gearbox. Are those castings normally painted? Best regards Peter
Romano, by saying no problem (JINX) means now a problem will happen because I said I have no problem. Like knock on wood for good luck. But the opposite.
When I pressure tested with air I pushed it to 30 PSI and did see a very slow drop over many hrs- At 1 hr virtually undetectable. I can detect no leakage around the pump with soapy water. Do you expect absolutely no drop after 12-24 hrs?
Depends how late the car is in 84. Ive seen bare gearboxes like Testarossa boxes but an 83 is painted including the cover. Things like the water pump castings, oil filter adapter and cast brackets are bare regardless of year. They stopped painting gearboxes the end of the boxer run.
30 is excessive to me, makes me think I could compromise something and have a failure later because of it like distort the pump seal which would suck
Stripped the upper plenums and wrinkled them so they match the runners. Finishing up the top before the plenums go on. WUR and fast idle valves were on clear zinc brackets instead of yellow zinc. I've seen them both ways so the best way is to just copy what the car had provided it appears original rather than change it to what you think it should be.

Ever wonder why FERRARI is cast on the underside of the intake plenums on a BBi where you can't read it? 400i uses it for its upper plenum. Once its drilled for additional studs and vacuum ports the 400i needs, it becomes model specific. Image Unavailable, Please Login Image Unavailable, Please Login
Left plenum had debris in it, you can see where I dragged my finger through it in the 2nd pic. Felt gritty. Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
as always really gorgeous. Back to the coolant system side- I was planning to utilize a waterless coolant such as Evans which would then operate a zero pressure and reduce all stresses on the pump seals etc. Jay Leno has used this in multiple exotics and highly recommends. any thoughts?
