There is oil seeping out of the between the head and block on my 81
This saddens me, another curveball. Not only that but now there is a steady leak at cylinder 4's hardline at the pump.. it looks as though it is not seating straight on.. but no matter how hard i tried, i couldnt get it to stop leaking.. Guess i'l try another set of hard lines?
However I do believe I will be having to throw a new HG at it.. So I was thinking what is the best way to do this?
disconnect everythng at the head that needs to be, and take the pump out to allow a god amount of room.. as i do not plan on removing the manifolds from the head. New coolant, and a new HG should be good to go right? Oh also I need new headbolts don't I?
CRAP parts site shows both 11X98mm bolts and 12X115mm bolts.. stupid 81!! what headbolts do I need fellas? i can't recall when the cutoff for 11mm was.
PS. Thanks a ton

With a NA you should be able to leave the pump and manifolds on. Just try and have a helper to set it down.

ok pump on makes life a tad easier.
However Tyler, do you know when the 11mm cutoff was through 81?

Nope. Probably whenever they ran out of 11mm stuff wherever you car was built if I was to guess.
You can pull the VC and figure it out based on the bolt head I think

Ok so for sure there is a noticeable size difference? what is the 11mm and 12mm reference to anyway? the width of the bolt itself? and then the 11mm are shorter?

I was lookin on GAP, and they don't show a HG for the 1.6's..
they show this: Volkswagen - Jetta 1, 1.5, 1.6 & 1.7L gas engine, '80-84 and then the 1.8L for the GTI's I was thinking of checkin the local place anyway..
Also I figure I will get 10 of each of the head bolts.. and then take back what I don't use eh?

Yeah I do that as long as my local guy is cool with it.
I have had the best luck with fel-pro HG. The victor reinz aren't bad either.

use diesel non stretch bolts if its an 11mm block. they rock. and ive had good luck with felpro and victor reinz gaskets too. only thing that makes them go tits up is way too much boost.

ok boys, went in search of head bolts and a gasket today.. Was not impressed with what I found..
Local parts place wants in excess of i think $60 and VW wants $85! Bolts also will cost me in the range of $40-50... Are you kidding me? I see HG online here for like $20.. I don't want some fancy shmancy metal one for crying out loud.. Just a fiber HG.
What to do here... My mother is visiting friends in Alabama, and she may just be bringing me home a HG and some bolts LOL. Does anyone have a good American site where I can find a good quality yet cheap HG and these non stretch bolts RoR speaks of?

So the car has a 3 notch on it right now, should I be OK with replacing it with another 3 notch?
It seems to have mostly stopped, it will need to be done obviously.. but if it will hold out for a few more weeks it would be appreciated lol. It's still bubbling a little bit at the HG between 3 and 4.

It's probably not uncommon for the HG to be the wrong one due to whatever a previous mechanic had on hand.
Your's is probably the right one since the usual thing is to put a thinner HG on to make up for lost compression and you have the thickest. It's best to measure though.
