Head Gasket

[theman53]

I like this thing if you don't have one already. It is a must on hydros I think, but had to add less oil after adding it to one of my mechanical head rabbits.

Oh ya! Those be nice for sure...

HG
ARP head bolts
Gp's (only if they are bad OR if you want to be safe)
Injector rebuild (absolutely)

what's the best place you've found for ARP head bolts, anybody know part # that would fit my application?
Where do I get the parts to rebuild my injectors?

Lifter/valve cover gasket (rubber)
Timing belt
Waterpump
Basic fluids

just did timing belt/water pump, but that's a good thing to add to the list.

I would recommend against the ARP's I have them in my TDI and have a slight HG Leak now, on TDIclub there are several guys that have had leaks start after installing the ARPs, while leaks with teh stock head bolts are never heard of.

   My ARPs will be coming out when I replace the HG.

[zukgod1]

I'll be danged. I don't have tons of mile on mine yet but over 20k and no leaks.

I think there are several others here that have more miles than that.
I wonder what conditions are causing the leaks..

Then I also wonder if the construction of the TDI head differs enough from the IDI head that this isn't a issue on the IDI engine.

I bought my ARP's from Summit.
But I think you have 11mm head bolts? I don't know though maybe someone will chime in.

ARP head studs for 11mm engines  204-4701    I've gotten them on ebay for around $100 shipped...  Worth every dollar and them some on the old 11mm blocks...


Very interesting about the TDI having issues with ARP studs.... They've been the only way to keep 11mm IDI's from leaking...   And they seem to hold up well on 12mm TD IDI's with crazy amounts of boost..   I wonder if it could be an issue with torque specs....

[jackbombay]

Sounds like the ARPs have a far better track record on the IDIs than the
TDIs, many people running a lot of fuel and more then 22 PSI has had
issues with the ARPs, there are a few guys that torqued the ARPs somewhat
 more than the instructions said to and they have not had issues, fwiw.

I picked up my ARP 11mm headstuds from headbolts.com, it came out to ~$110 shipped.

[maxfax]

Are the ARP studs specifically made for the TDI?? Or it like the ones used in the old 11mm IDIs?? (Gasser studs)  Maybe they need a tad more torque???   Don;t know much about these new fangled TDI's  Finally moving up to 1.6's...

this is probably taboo, but i'm kinda low on cash right now so it's the route i'm going to have to try.

the plan is to just get regular oem couple dollar bolts for now and then down the road, replace them w/ the arp's.

how bad would it be to do this; i'm thinking down the road, w/ all the oem bolts in place, take one bolt out at a time and just replace it w/ an arp one, one-by-one.   :?:  :?:  :?:

[zukgod1]

Yes you can do that.

Just keep the boost down and you will be fine with OE bolts.
Just sucks to do it again later but at least you can do it without removing the head.

[maxfax]

Which bolts does your engine have???   (maybe you already mentioned this and I missed it)  11mm (Hex head) or 12mm (Tripple square head)..

  Thats ow everyone installed their ARPs on TDI club, nobody ever had issues right away, but as mentioned many of us had issues later, mine were fine for ~20,000 miles. I think if I had torqued the ARPs more than the directions said there would not have been an issue. The ARPs that fit a TDI are actually intended for a cosworth gasser, where peak cylinder pressures are certainly way lower than a Diesel.

  The question is, at least with a TDI, how much to torque them?

:shock: I have the triple square type (for sure) but I assumed they were 11mm (I thought 11mm was stock and 12mm were upgrades...)

Are all triple square's (head bolts) 12mm then?

Also, where can I buy a freakin triple square driver!?!? Dumb local VW dealership doesn't sell ANY tools! Found out I had a Fastenal store just down the road, but the dummy behind the counter didn't have a clue - looked like he belonged in a Amberzombie and French store... stupid punk.
