Jarred's Mk 2 GTI & silly questions.

[benough]

Well some blokes know already, but I've been having problems recently with the mk 2 using lots and (LOTS) lots of coolant.

Took it down to Volkspower today to get it checked out, cyl 3 is filling with water! Most probably the headgasket, with any luck, the head will be fine, but I'll have to take it somewhere to get it checked out while it's off.

Oh man what a bitch! In hindsight it wasn't too hard to get it off and now you can get a MK3 dump pipe and clean your head up with a bt more compression to boot!

[Jarred]

Yea, I'll defiantly put the mk 3 DP on now. I'm stuck with what to do with the head.

There's no point spending money on getting it ported and stuff, I'm hoping it's not damaged, so I can just pop it back on, and get brapping again, but at the same time, the lifters are getting a bit noisy, and I wouldn't mind a slightly better cam.

If it only costs $350 for a complete Audi 2 litre long motor why bother to repair your motor?

[Jarred]

a) then I have to do an engine swap, and whilst the engine may only cost $350, I'll end up buying other parts at the time and it'll cost me more.

b) then I have a new engine, and potentially a new can of worms. ie new problems with the 'new' engine,. Realistically, if I put a new engine in, I'd do a whole bunch of seals and gaskets (inc the head gasket) at a minimum. (part of the do it once, do it right principle)

c) I've driven in a mk 2 with a 2.0 bottom w 1.8 head, and a few other mods (basics: chip, AFM etc) and I can't say it went phenominally better than just my (standard even) 1.8. I'd prefer to spend the extra money on suspension & brakes. Sure it was an improvement.

d) I can't be bothered! Just want to get it up and running again. (only have 1 car atm, and this one wasn't meant to be a 'project')

If the head is damage and needs replacing, I'll hunt around for a cheap second handy, but If nothing comes up (at a decent price) I might look into a complete engine.

Just a few ideas off the top of my head anyways.

[sports racer]

My car has the 90hp engine so a 115hp 2 litre swap makes sense for me. What has been done to your car to make the difference so small?

[Jarred]

I'm not basing my decision based on factory numbers. I'm basing it on experience. The 2.0 with 1.8 head is meant to be more comp, more capacity and hence more power, but when I was in one last, it didn't impress me that much, so I'm not in a hurry to go out and do it. This isn't my project car, it's my daily, so I need it back on the road sooner, rather than later.

I got an offer for u jarred, u can have my old 2.0l engine for free if u can work out how to get it down to u

[Jarred]

Dammit pedro. jsut damn. I'll come pick it up at Nats!

So I took the head off today, didn't take too long, but a mk 1 is just so much simpler! haha

Only took about 3 hours mainly due to the various manifold bolts being PIA's!

I havn't taken the injectors out, is there a special tool for that??? ( I dont want to break them afterall)

I had a quick look around the offending cylinder (3) and I've found what seems to be a small something, between a water gallery and combustion chamber, so I'm assuming that's where the problem was! Looks like I'll have to get the head shaved/machined just slightly. I'll take it down to RG Baker tomorrow morning, (on the bus ) and see what they say! (see last pic

yum!

You got off lightly!

I had about 3-4 of those.



Had to get mine welded up and ground. It was shiny as a bitch when it came back though!

[Peter Jones]

Ah well, it'll go better when it's fixed.

I know you've got a twin pipe manifold to go in there but this method of expanding the clips of death is worth mentioning anyway.

How far are you going with the reco? If you're just going to get it skimmed I'd suggest you do the stem seals while it's out and de-coke the valves too.

I've got a tool for pulling the k-jet injectors, not sure if the digi injectors just pull out the same way.
