Re: GTO Track Project-Here we go.

Well I've private messaged and texted his last known mobile number, and nothing. So getting hold of him is a no go. I think his son works at Pick a Part in Wingate if your keen enough to reach out there?

When you checked the bolts, did you mark their position, crack them off first and then re-torque them? Even the "loose" ones tend to be frozen in place.

Yep. No Loose bolts.

Re: Heads and MLS gaskets.

Sat 09 Jan, 2021 10:39 am

Box you might be able to help me here. If Steve was reading this I know he would as well especially with dissimilar head planing depth/dimension/amount (hard to describe).

Anyway gotta go MLS. I know you can get different thicknesses of such. Thicker the better one would think, but too thick would leak I would think. Any advice anybody? Haven't googled this yet.

One of the heads (the front one) I have bought from a wrecker (because "THE WRECKED" car had a head gasket problem) appears to be recently reconditioned. It's all shiny etc. I have done a comparison and it does look like the front and rear heads are identical, so you can flip them. Ok both these heads appear to have been planed to the same degree. So I wonder how much? can you measure this. And following on from that thought I wonder how different they are to my existing good TT head in the race car? Hence comment re Steve.

I have got my original TT cam set in the race car at the moment so no mixing them up.

Box  (ref an interesting current topic NZPC ) . 400kw atw on a stock motor. when you built up the forged motor and it sh** itself twice what was the reason? Rods? Bearings? Oiling? assuming you used a 4 bolt main and forged Crank? Can you say?

If you want to keep it cheap, these used to be my go-to MLS head gasket set (as recommended to me by GTOrange): 
https://kerzan.co.nz/index.php?route=pr ... earch=6g72

I've since switched to using genuine Mitsi MLS head gaskets. Don't know about thickness, never cared enough to measure them. 

Off the top of my head, the overall head thickness/height can be measured and compared to the numbers in the manual. I'll see if I can find it.
There are also depth indication castings in the bottom of the head that wear down as you plane them.

Re. the blue car, I didn't touch the bottom end internals. It was done by a local engine reconditioner that I recommended. They've always done good work, I haven't had any issues with them and wouldn't hesitate to use them again. Anyway, it demolished main bearings (and cranks) on the dyno both times, both while being wound up on E85, both by the same tuner, both times on a horrible old Australian "EMS" aftermarket engine ECU. Funny story, it was the same shop that ran my car on the dyno with the front wheels strapped down - well maybe they didn't. Or did they? Who would know.  I blame the tuner. 

By that point I had left the motor trade, a local workshop pulled it all apart, the engine ended up going off to someone that does Evos and then the car went over to Tauranga to be tuned as recommended by the new engine builder. They finally threw the EMS ecu in the bin and wired up a Link. Something was done to the oiling system in the block, I think the galleries out of the oil pump were taken to with a die grinder to increase flow or something along those lines. You'd have to ask the owner if you want more details. No problems since. 

4 bolt block & stock crank. It's on a new genuine crank at the moment. 

If you want to track down Steve, go open an account on 3si and reach out to him, his user name is stevecooper or something like that.

Well by sheer chance I found one... after about 10 years of looking!....well bits of one. Here's what I don't have...

1 x Crankshaft (nitrided steel) I have a spare Cast Crank and am not overly worried about this but interested if there are any out there...
1 x Sump Pan. I really need this item.
[font=Segoe UI Historic, Segoe UI, Helvetica, Arial, sans-serif]1 x Lower timing cover. Nice to have an uncracked one.[/font]

[font=Segoe UI Historic, Segoe UI, Helvetica, Arial, sans-serif] [/font]When I build up this block with Forged Pistons and better Rods Iwill do a full build with new seals and bearings and oil/water pump etc. If you have any of these bits that maybe you have never used or don't think u will use let me know... 

Cheers.  here's a helper.....     http://www.wrenchjockey.com/Webpages/4boltPictures.html
