Looks Great.... you painted them and media blasted the cam housing ? Mine look very similar!

Keep itup!

I stop at the shop and blast a couple of parts each day, one step at a time....

the paint is International Harvester Red preimum farm implement paint. it is supposed to stand up to head, grease, oil, wear, and just about anything else one could throw at it. at 7 bucks a can from Tractor Supply it ought to!

After blasting the covers, I put them in the dishwasher and the surface came out a lot smoother than it was before. Much better finish than just painting after blasting.

You should get the correct length M8 studs for the two that are excessively long on the intake side. Looks good though

You WIN!!!!! I was wondering how long it would take for that to get noticed and I will!

You cetainly have some photo skills! what camera are you using?

Give us the details on the build........

Cheers

The camera is just a Nikon D2X, light box above, gel on the back light, nothing special.
I recently acquired a 70 911T.
I had just replaced both rear wheel bearings and it was so smooth, but only got about a hundred miles down the road before the rocker shaft fell out.
It has 125k, was driving to Corpus for an Ag reunion when a rocker shaft slipped out and I lost a valve with the consequent oil deluge. The motor had the usual oil leaks so I figured it was time. I've been air honeing all the parts that will get paint. New aluminum jugs with new pistons and rings, valve touch up, new bearings of course, oil pump is good, it has the tensioner upgrade but I'm getting the collars to prevent tensioner piston from failing, new chains, new upgraded oil pressure relief pistons and springs, oil passage restrictor upgrade in head. Micropolishing the crank, glass beaded the rods. No major performance mods, just trying to put it back with good parts and procedures. The car was originally blue but has been done in black everywhere. The doors have some serious rust at the bottom, other than that it's solid everywhere else. Just a damn fun car to drive, almost as much fun as the Alfas I had in the past, well maybe a little more fun

Alfa's are fun

Sounds like a good project, you are in good hands on this board.

Cheers

You say the oil pump is good and you are using upgraded pressure relief valves and springs. These statements don't go together. You need a later oil pump with case bypass mod or you need to keep the old pressure relief valve and spring. I don't think you can put collars on the hydraulic tensioners.

Humm, John at Pelican led me through what I needed. The pressure relief upgrade is a piston without the holes in the side. We discussed my oil pump and he recommended the new oil pressure relief solution.
We also talked about the tensioner upgrade and he recommended the collars for those tensioners. He said he had them on his engine.
If this information is not correct I want to find out now and not later.

Eagledriver · 09-21-2007, 07:10 PM

My information on the pressure relief valves cames from Bruce Anderson's 911 performance handbook. He says if you mix the pressure relief valves with the wrong case bypass you will introduce oil pressure problems. The relief valve with the holes is for the old pump with the bypass that goes into the bottom of the case (standard on pre75 911 cases). The new bypass is for engines with the updated pump and bypass that goes to the input galley of the oil pump(standard on post 75 911 cases).

I haven't seen a collar for the hydraulic tensioners but maybe that is something new that I don't know about. If they fit then probably not a problem using them.

I don't know who John is but maybe he can explain to you about the 2 types of oil pumps and what the bypass mod is. If he knows all about that then maybe he is right about the pressure relief valve upgrade working ok with your pump.

I certainly appreciate the info. Knowledge is power and I'll double check with him. Got to give them a call Monday anyway, got my parts today but no book. Still need to order a couple of exhaust studs and rocker cover studs and a couple of other things. I'm still cleaning and preping so there is no great rush.

Upon close examination of the oil pump I noticed the pick up tube seemed to be loose. I gave it a gentle tug and it came out of the housing. It appeared to be jb or devconed as the only means of attachment. Is this right? Should I re-glue it back in. If that is the way it's done I wish I would never had found out because having my rebuild depend on how well something is glued in to something else is rather disconcerting to say the least.
