Hi Guys,

Thought I'd do an update here as I haven't posted much since my intro. http://z31.com/forum/viewtopic.php?t=9986

Got the engine out finally.

The rear crank seal was split.

Crankshaft looks ok. Sorry for the blurry pic, taken on a mobile.

Clutch, looks a bit worn. I think I better get a new one since its all apart.

Bell housing, very greasy from the broken seal.

Cleaned and painted front cross member ready to go back in. Will these engine mounts be legal here in aus?

Cleaned up oil pan, need to paint the outside.

Passenger (left side) of block seems not too bad, honed it a little needs a tiny bit more.

Drivers side, much more worn, still got to hone more, but I'm scared of taking too much out.

Close up of the worst cylinder wall.

I ended up taking the block to a shop to get bored out and had to get oversized pistons and rings. It will be worth it though in the end.

Also did some other bits and peices.
Cleaned and painted struts. The one on the right has the new Eibach Lowering spring. The shocks in these are Pedders comfort and are practally new, only done 50kms or so when driving the car to our new place.

Cleaned and painted guards (I know its not the best of jobs but its not going to be fully visable).

Pedders Comfort standard height spring vs Eibach Lowered with no load.

Installing lowering spring with poly spring seat.

Fully recon power steering pump and brand new water pump.

Fully recon power steering rack (this cost heaps Sad

).

New clutch kit.

Got my bored out block back with new oversize pistons, rings and bearings installed Smile

Just need to paint the block. I guess I should have done that before sending it to get done?

What "over bore" did go to and what size pistons?

I think it was 0.025mm or 0.5. Can you tell from the pistons?

That is a .5 mm overbore. My question is who makes em? Are they forged or cast? I.E. What was the cost on those babies?

I think they were around the AU$360.00 mark for the set. All the work they did on the block cost me AU$905.00. That was for boring, new pistons, rings, main bearings and to assemble. I already had the rod bearings from Courtesy parts.

Finally I was able to get some stuff done to my car Smile

Not anything to brag about but its a start.
Started to re-assemble the engine and install it back into the AE bodyl for now to get it running.

New Rear seal installed

New front seal and oil pump installed

Oil Pickup installed.

Sump installed

New clutch kit installed

Engine back in car

Cleaned starter motor re-installed

New water pump and original coolant lines installed

Drivers side head back on.

Passenger head is on.

Passenger side Header is on. There's no clearance issues at all with this one.

Drivers side is a different story.

Touching the bell tower.

Close to the brake and clutch lines

The brake lines are close. The line not hooked in place is the clutch line I replaced years ago. I need to bend it more to shape and cip it behind the brackets.

If I put a trolley jack under the drivers side header and bend it upwards and off the bell tower, will this put huge amounts of stress on the exhuast studs and brake them off? I've already snapped one on the passenger side (Damn brittle old studs!! I should have gotten the taken out and used ALL NEW ones, the old ones were already in the heads when I got them back from being recond.). This can wait till I take the engine out again for the new body. Hopefully it doesn't leak too much.

Got the rockers on. Cleaned them up pretty well Smile

Half way done on the passenger side.

Broke another bolt!!!

Second last on the right. I might have to invest in a better torque socket drive. It just kept turning till it snapped. Felt firm but not as tight as all the others.

Got the bolt out. First time a bolt extractor worked for me Smile

Rockers all back together.

All timed and cranks free. Doesn't hit anything. I did a compression test at this stage too and all cylinders tested good. Above 170psi.

Started to grind and polish the intake runners.

Should get this finished this week and hopfully start the engine up on the weekend.

Thanks guys.

Not much of an update. I've been busy with other things and haven't had much time to work on my Z.

Finnished cleaning / grinding out the intake runners.

Installed the new fuel rail and injectors. New FPR too.

New intake gaskets. I smeared a little bit of oil on all surfaces of these cos I had a coolant leak here when I changed these previously.

Bypassed the intake collector coolant lines.

I got my rocker covers on. Not sure if I will stay with this colour or go with my main body colour later on, but it looks allright. Has a few scratches on it already from installing. The camera flash makes it look more pearlescent than it really is.

I'm all set to install my plenum but I need to get it professionally cleaned out. There's only so much a spray can degreaser will do and its still full of muck, can't get into it properly. I'll try n sort that out this week.

Here's some pics of the cleaned out plenum.

And here's a link to a 30sec vid of the second start I did. I'll get a better quality and longer one once I fit all the belts and ad coolant etc.

Ok, better vids now.

Theres still a wired sound from the harmonic balancer or somewhere around there and the altenator is making a squeeling sound after I cleaned it.
You can hear the leak exhust leak where I broke the stud off on the left side.
http://www.youtube.com/watch?v=_a6F56O5dlI

And the exhaust note. Sounds good except from the leak on the left header.
