hi as most you know from my post i had min pop its aux belt and tentioner and radiator
after i fixed all that was still pissing water found a blown hbv to coolant bridge hose fixed that
whail i was at found a vacuum res on muiltiram was busted fixed that and all vacs
thing is since then engine in running best it ever has its only done 105 thousand
and its actually getting 30mpg on motorway if you take it easy now and much more punch low down cam belts and water pump been done
its had abs ecu done crank sensor new wish bone new pipe cam cover been done prity much everything
only thing that needs doing is a few counsel bulbs
i love my miggy body work in mint bar bit of rust on bottom corner of back passenger and arches need doing other than that its lovely and scuff on frount spliter
thing is im paranoid about head
since aux belt fiasco
ive done about 500 miles
still losing tiny bit of water bu not much 1/4 of header tank in few hundred mile some of it could have been air but there a drip somewhere
no smoke
don't apear to be oil in water dip stick is fine
no manaze in dipstick and oil seems fine bar need a change soon
but mayo in oil filler neck is worst that its ever been iv been doing quite a few long trips
ie coast luton to south end
luton to oxford shire yesterday
iv been wiping it and re checking all the time but still it seemed more that it ever has since if had car
yesterday it was a better tiny bit in there when i got back from oxford
the wishfully part say well maybe it need a oil change an since it running more efficient since i found vacuum link it just a bit of condensation
and how can it run that well if its going on head
so im just not shaw what to do and am a bit paranoid if head ok id like to sort arches
fit and spray new splitter fix and spray bottom of door and it mint again only got two tiny stone chips on bonet then
if it aint ill get shot
just wish i could figger out a way to be Shaw it aint the start of head going
-
Have a sniff test done on the header tank?
Have you got GM oil in it?
-
yep genuine vx oil never put anything else in since i had it.
think that maybe try a sniif test but never seen em for sale anywhere
-
Have you had the system pressure tested?
-
just got grarage to do sniffer test and it dint change coulur
so im guessing gasket must be ok
as for presure testing coolant iv not yet but i got a compressor so ill have to find a spare cap
so far re leek new radiator top hose there a not long new hbv in there and a new hbv to coolent bridge hose put on last week
i changed heater matrix as well after it burst in style few mouths back
chucked a couple of bottles in there of bright blue food die as well
still cant see naff all coming out anywhere
as head seems ok i can live with a drip/small leak but would be nice to find it
be more conclusive proof head is fine but there want no color change on sniff test
i did look at oil cooler plate but that seem fine when done hose to coolant bridge last week
im half tempted to chuck a bit of rad weld in for now but for peace of mind id like to know where it leaking from
-
Mine used to leak from an o ring at the back of the engine, a steal pipe runs in there.
-
how easy are they get at
-
Could be the coolant transfer pipe "0" ring seal at back of head as mentioned.
Its abit of a pain to get at and as with most things at the back of the heads requires loads pulling apart first.I foud it easier when I replaced mine to almost kneel on the front slam panel and lean over,but still requires a fair level of dextresity ;D for the sake of a rubber "0" ring
-
A weep from the headgasket at the rear of bank 2 is not uncommon.
Another cause of continuous, slow, coolant loss is corrosion of the coolant transfer pipe. Either pinholes in the pipe or corrosion on the outside of the pipe acting as a wick where the top hose slips on.
Also worth checking the heat exchanger cover plate and block & cylinder head core plugs (if you can get to them....)
-
dint think of core plugs
one thing i need to check when i done hbv to coolant bridge it was a bit of a bodg up as
it had split at bridge end right at hose clip i had some warter pipe with same internal diameter but its was to shaped to use without it kinking
being in a rush to sort as i needing transport and rest of hose looking fine i just cut a inch or so off end and put back on
so it could be coming out there but cant really run it to see
so maybe if get the right one from dealers and have another look and while im in there pressure test it
buy the way which is bank two :-[
driver or passenger side
wish i knew i news some one woth one them felxble things
