Default Engine running!

The engine fired up and runs! Just a few cranks to get fuel up to pressure. Oil pressure came right up, too. Not well as it's not tuned up, yet. Running far too rich, but that'll come.

Wrapping up the re-assembly. The air pump was removed and a 4L-210 belt fits snugly between the crank pulley and the fan.

To make the exhaust fit the '85 manifolds, I cut the right-side tube just in front of the muffler. The flanges line up well except are separated by ~4" straight fore/aft. Thinking poorly, cutting in the straight part ahead of the muffler makes the splice fairly easy but the new pipe position covers the bolts on the lower bellhousing. When I get it welded up, I'm going to have that repaired and make the extension splice near the manifold flange.

I'm using Valvoline VR1 50 weight for the break-in. I think it's the best oil that's easily available and not too pricey at $5/qt.

Otherwise, just bolting things in and up.

Default Clutch master bled

Got the clutch master bled today. It wasn't that hard but it was messy. I recalled someone saying that they had bled it "backwards" by forcing fluid up from the slave. That worked great.

The slave was OK once I put it back together. Not sure what happened but the rod was in the catch can and I'd shot the piston out. ("how'd that get there?!") The slave was new a couple of years back so I reassembled it and put it back in.

I've got a vacuum pump with a brake bleeding cup. The cup has a top with two hoses attached. It seals tightly. Normally, a hose goes from the top and to the vacuum pump while the other hose runs down into the cup. When drawing fluid in, it goes to the bottom and just air leaves from the top. I used that to bleed the brakes and it worked well.

To bleed the master, I filled the cup and attached the "inlet" hose to the hard line at the slave. I removed the slave to reduce the volume of fluid needed. Then I very gently pressurized the cup from an air compressor to force the fluid up into the hardline and up into the master. Some fluid sprayed around and the brake fluid runs out pretty quickly when the line was not plugged. Took a couple of tries to figure it out. Had to top up the reservoir along the way.

After forcing a full cupful (maybe 2/3 cup of fluid) up into the system, and no air, I quickly attached the slave and vacuum bled that. I was surprised at how solid the clutch pedal felt. Ran the car and the clutch opens great with no dragging.

Default Blow-by catch can

This catch can is for the blow-by coming out the top of the oil filler. The connection at the lower plenum for that hose is plugged. It's a 2 liter can with a handy sight gauge and a drain plug.

The can is mounted on the right side of the engine bay where the air filter for the air injection system. There are three 6mm bolt holes there but none point straight out. I used a piece of aluminum to fab a plate and that's bolted to the wall with the three holes and the can is bolted to the plate. It's really solid.

On my other car I had a lot of problems with blow-by carrying oil mist back into the intake. This leads to the well-known problem of 928 blowing a lot of oil smoke at high RPMs. The windage kit and tight rings should lower that but routing the blow-by out of the engine stops it all together. On my other 928, checking the catch volume is a good way to see if the oil ejection issue is controlled.

Something else on the engine is an oil control plate from 928 International. That goes under the oil filler to block oil being thrown off the crank from going into the stock separator can.

Default Engine bay all assembled!

Whoa! What's this? All the engine bay parts are in! Also looks like months of work and years of planning. A couple of things to note:

The air intake tubes are replaced with 3" high-temp brake duct. Someone, somewhere, said the stock tubes are good to 350hp. The engine should be near that. This is a bit noisier than the stock "venturi tubes." The trick to installing them is to remove the outer cord warp and the inner wire from the last inch or two of the tube on each end. Then the stretchy tube will slide over the end parts.

The stock cross-brace is replaced by a nice, shiny, stiff unit from 928 Motorsports. This was a special order with no engraving.

In the middle there's the adpator to take the outlet from the oil filler cap, about 1", down to a 3/8" barb for the hose to the catch can. It's not a real project without some parts from the hardware store's plumbing aisle.

The car's down on the ground. Looks like the ride height and alignment will need some adjustment before it'll be really roadworthy. Way too much camber for sure.

After that, it's on the road!
