Your list sounds pretty good , arp 2000 will be fine for a vf 34 , I put stem seals in , got clearance reset , you’ve pretty much covered everything really ... I used genuine gaskets .
You might get awhile out of it yet .... mine was slow process , actually the gasket was still pretty good but blowing over from old stock head bolt stretch by the looks of it . Don’t forget rear main seal and possibly reseal the sump .

Thanks mate, I will take note of changing the rear main seal, it's a good opportunity to change it while the engine is out. :thumbs:

I will more than likely get a full genuine gasket set and the sump will be re-sealed when the oil pickup (and maybe forged pistons) are fitted.

Did you fit forged pistons? If so, what are your thoughts?
Another option is to go for a STi shortblock and have a fresh bottom end. :dontknow:

Is the STi oil pump good insurance or not really worth it?

The head gasket is not bad yet, I wouldn't of known it was starting to go if I didn't check for bubbles in the overflow bottle. Hopefully it holds out for a while.


Should I attempt the rebuild myself??? :dontknow:
Will see what happens when the time comes.

No worries mate , of course it will vary but I got a bit over a year I think between first noticing strange things going on with the coolant and getting to the point of - it’s time to fix it - though don’t miss having to syringe the coolant back outta the overflow most mornings by the end

Oh yeh of course if your pickup off etc the sump will be off , late sg prone to cracking I’ve heard so good call .
nah no forgies here , my sump was weeping a bit so that’s why I mentioned that ( there’s no gasket afiak)
Your plan with forged sounds good , I’ve done very well with the stock pistons but they are considered a weak point in the ring lands. The short block was very tempting but stretching the budget at the time and the price of second hand lower k wasn’t worth the gamble so mines just got the arp 2000 and put back together- at 260thou
Still going strong nearly another 50 thou later , so I would go yours with forgoes over a new bottom end unless you have the cash for both

I’ve done head gaskets on ford sixes no probs but chickened out of doing the suby due to not confident with the stud kit / timing gear / time / certain tools , if you got all that and or the patience to learn you could consider it - motor out again bro if ya **** it up though
Don't know enough about the advantages of the 11mm pump , hopefully someone in the know will chime in there

Same here, I rebuilt a few old school 4's & 6's back in the day but finding time is my biggest problem at the moment.
As much as I would love to have a go at it, I have work and too many other little projects going on at the moment so I will probably hand it over to a professional.

I will see what happens when it gets worse, at the moment I have a temp alarm set for 95° (I haven't see the temp climb over that on the torque app yet) and I am not driving on boost as much.

Mental note (and typed here) I might fit some EGR blanking plates too.

Does anyone have dimension of the plates so I can add them to my list of things to make. :lol:

If you are taking the heads off, you dont need blanking plates. Just run a 1/8 NPT tap through them and put a steel plug in. The heqds will be on the bench so very easy to tap, and clean up after. The blanking plates are pretty expensive for what is literally a few dollar part. (Think ive seen prices as much as $100 for some)

The hole is literally the perfect size to accept a 1/8 tap. Its like they knew it would need blocking off :dontknow:

Good thinking Bram. :thumbs:

I was not really planning on buying the plates even though I think you can get them for about $30 on ebay.
If I made some blanking plates, the only real cost would be my time.
Plugging the heads sounds like a good option. :drinks:
