Rebuilding engine pixs

My friend and I rebuilt his s4 n/a last night, didn't have any real problems but we haven't started it yet.... Still have to get the front cover on/oil pump assembled and check end play..

That's gasket maker. Helps seal.

Although (In my books) Blue is the weakest kind.. Shouldn't you be using high temp stuff?

Looks neat though.

Thats the supplied hylomar, used for seating the water O-rings. The red stuff is brushable gasket maker

I have another s4 n/a at home, I'm going to rebuild and possible BP

Damn, that looks nice.

In the 4th pic I think, are you putting down some oil? Looks like it just wanna be sure.

Also, are dropping the housing onto the rotor? I have heard this can be problematic. Just curious.

as long as the housing fits over the rotor, it's all the same. I've seen them done both ways. It's like saying you should alway put on your left shoe first.

I do put my left shoe on first, I was just wondering if any complications occur, like will the rotor align when you first start to drop down the housing onto the dowel pins? Just curious as to how you go about doing it.

Nice.
I wish I had extra money to get a engine from a junk yard so I can play around rebuilding it.

I think "dropping" anything into place probably isn't a good idea .

i find it easier to put the housing on after the rotor. in fact if you check to make sure the rotor is in the right place youwon't have a problem. i like to slide the housings down the dowel pins that way i know the water jacket o-rings do not move because you don't have to reposition the housing.

great pics!! i wish i had a garage, i would rebuild a j-spec in a sec with street port. it's enough hassle to remove the turbo in my townhouse parking lot. anyways, looks great man, good luck. i want to see some pics if you decide to do a n/a w/ bp.

Well on the rear rotor you point an apex seal toward 12 o clock, then make sure each apex seal is on the combustion space and not sitting over the water jackets. Then the rotor housing slips right over, we carefully lowered it down, having 2 people helps. Both ways seemed to work fine for us.

The oil that is being put on the rear stationary gear is a heavy lube( 1/2 motor oil, 1/2 STP oil treatment). MMO is the light oil being put on the rotor face/side housings..

We ran into a big problem today, one of the T-bolts on the port side is not threading. We believe the female threads on the front iron are stripped. All the T-bolts sit up about a 1/2" before being threaded, and this one drops right down. We even tried the #17 M marked T-bolt( which is longer), it catches then slips when tightened down.. We believe it was our fault too, we did not loosen the T-bolts before we hit the with the air impact gun on disassembly.. Make sure to use a big rachet to break them free..

Good thing I have a spare front Iron, just going to have to postpone the BP s4....

We also are going to get an engine stand and adpater, no more of this ghetto ****. I have also setup a nice work place for this in my basement..

engine assembly grease works much better than MMO and STP, I coated my rotor housing, rotors, oil pump, gears and everything else in the rotating assembly, trhe reason I use this in stead of MMO is that it won't get burned off as quickly and it sticks to the surface.

On my last rebuild I used assembly grease and my engine started up on the first crank!

Care to share the brand name and such?
Sounds like it worked really well for you, maybe I'll give it a try.
