progress on GU 2.8 over pressure re post 42387

howd'y again,

You only rebuilt yours not long ago hey?

If you did thats what is causing me some pain, I would have no probs rebuilding the top end if it would give me years of trouble free motoring but the idea of spending $4000 on a new top end and having to do it again in a couple of years does not excatly excite me at all, If it proves to be the big one I will be trading mine in thats it. I am at the stage where I have not sunk big $$$$ into it and feel I should keep it, I could walk away from it and lose $2000 that I am comfortable with. What test are you going to do with yours? leak down? or TK (Co2)???

Good luck mate

Stefan

Probably another Co2...

I was hoping for the years of trouble free motoring as well. The first problem of cracked head was due to some overheating, can't really blame the car for that one, although I got no error light and it didn't go all the way on the gage. That one was a new head. The mechanic advised the bores were a little scored, but it would be OK for a fair while. I got a new radiator and thought I'd be right for years.

The second time was a small coolant hose near the oil filter that exploded and dumped All of the coolant, which I didn't detect untin I lost power, as dry temp guages don't work too well. I decided on a full rebuild then as the bores had scoreing before this event(head was machined, not cracked), . I then fitted the low colant alarm (should be std on all cars)

This was about 2 years ago. I thought my troubles were over, so took the plunge on the LPG. I'd noticed a very small amount of coolant loss prior to the LPG fitment, but put it down to an ageing radiator cap. It has now got worse and looking like another head....if I go ahead and fix it.

It sounds like you could be nearing my first stage. Knowing what I know now, after the first head the car would have been down the road...Having said that, the events were not really the car's fault. Some were mine, some were bad luck, and the last one is a mystery. I think this motor doesn't like me, so I think it may have to go. I'd like to get another 6 months out of it, but at what cost.......

If I knew it would be just a head gasket, I could probably get away with about a grand, and get that money back when I sell the motor for a 6.5. If its cracked, 4 grand I will never get back.....

6.5 diesel, 25 grand I will never get back, but I'll have a great car for the next 10 - 15 years at least

Decisions decisions

I am heading that way......some goop in a bottle....nothing like a cheap fix!!!

cheers stefan

It worked for 700 k in mine, now its started bubbling again (as I said above)....might have to put 2 bottles in this time!

Cheers Andrew

Trust me if you had a problem you would know about it, enjoy your good run with your 2.8 mate, there is always goodn's and badden's in every type of car, you only ever hear about the bad ones.....aka 3.0lt sure maybe 200 have blown up, but 1000's have not..

Cheers Stefan

You could be on the right track, Two people have given me examples of water pumps doing the same thing to their car....opps now 3 lol.....one was a toyota surf....one was a VW of some sort, and now your Disco....The mechanics said to me no way can't be it....been in this game 30 years ect ect ect. So since he is perfect who am I to disagree!!!! LOL. Grave yards are full of people who's doctors were never wrong! I am going to do the pump anyway real soon as its only $100 for one so its worth a shot I reckon.

Cheers Stefan
