I'll split the motor and gearbox into their own sections for better grouping within this post.

Motor

Nice to have the motor out of the car, it's been a really great package ever since installing, definitely beyond the moon for choosing this setup. I had it rebuilt to OEM spec when doing the motorswap, due to some bore wear on 2 of the cylinders, and it blowing a fair bit of smoke.

She's held up well, except the valve incident last year where 1 cylinder had been on 40psi for a few track days. The plan for now is to go over it and replace anything thats leaking, chuck a timing belt on it and clean it down.

Inspection

Rear main looks fine, thankfully. There was some oil build up in the flywheel cover plate as you can see, tad unsure what this could actually be as it could only realistically be the rear main or sump gasket, both of which are fine. I'll clean it out anyways and keep an eye on it.

The PVC canister looks to have a minor leak which has been going for quite some time. I can't remember if the engine rebuilder or I reinstalled it, but a lot of silicone was used on the o ring section when there didn't need to be any. You can see from the 2nd photo it's been leaking onto the top of the exhaust.

Removed it, cleaned up the area and the PVC itself, removed all the silicone on both, fitted a new OEM o ring and reinstalled, happy days.

This is the damage on the passenger side engine mount. I'm going to guess a lot of it occurred from the torn mount of the other side of the bay for the gearbox. This won't help with the engine running, so will need to look to replace in the future.

Exhaust ports

I noticed around the headers there seemed to be some dirt build up. The way it was formed lead me to believe there could been a leak from the gasket.

Looking at the gasket in the photo below, going from left to right, it looks like cylinder 2 has some markings on it which could have been something leaking. Inside I could see one of the exhaust valves were wet, so I'm guessing oil is leaking past the exhaust manifold gasket? All just assumptions, for now I won't do anything, but will need to in the near future I think.

Below are photos from left to right of the exhaust ports themselves, which you can see a lot of carbon build up. Wonder if this is affecting any performance? I wiped out anything that was loose by finger, didn't want to remove all of it in casce it fell back into the head.

Timing belt

The current timing belt looked fine to be honest, but it's been through a lot of hard km's over 6yrs. As the engine is out of the car, it's only right to do the timing belt now. Waterpump was assessed and didn't really need to be replaced.

New one on!

Misc

That CV grease again..

Everything looking clean behind the motor!

Gearbox

Alrighty, gearbox time! When I did the motorswap 6yrs or so ago I used the same flywheel + clutch that came with the DA9. Upon removing them it became apparent they were already very worn. My mate took the flywheel to get it machined through his work and they said theres nothing to machine and it was stuffed.

The motorswap already used all my money so I couldn't afford a new flywheel + clutch kit, so I threw all of this back in. It lasted all this time, being thrashed on the street spinning 1st/2nd/3rd, all the track work it's done.. It hasn't had an easy life. I knew it was time to replace it, one reason that made me happy to remove the engine & gearbox.

Upon removing the gearbox, everything looked fine, but when removing the clutch, we found the cap had come off the flywheel bearing and it was missing some ball bearings. I've only just noticed now, but the first photo below you can actually see the cap dangling!

The input shaft looked quite dry, covered in surface rust. The thrust bearing was very much the same, felt sticky. The grease behind the fork was a sticky sludge, and there wasn't much of it.

Inside the bellhousing was quite dirty, and I don't recall cleaning this when originally installing. Funny thing this time round I forgot to clean it as well. So I decided to give it a quite scrub just before we installed it with some degreaser and a tooth brush. Not perfect but good enough.

I went with a standard Exedy clutch kit with their lightened flywheel. Looks a great bit of kit, and should be perfect for my application. Don't need heavy duty with this level of power.

Fork points greased, shahft and thrust bearing points greased with the provided lube from the kit, and of course thats the new thrust bearing from the kit.

Here's the old kit for reference.. Solid setup!
