    Pressure cap not releasing pressure!!

    I had somewhat similar symptoms, or maybe still have....:-) On another tread called overheating still.... One thing i found was rad overflow outlet was deffo blocked. I took the small hose off and reved car with cap off (cold) and got nothing but dribbles. In fact you should see water flowing...

    steering box adjustment

    Ok, its really only just off, i think one turn on drag link adjuster or less would do it, but if it knocks box off center too much i guess its intermediate shaft off again (pain in the ass getting that off doing head gaskets) and move a spline or two. Maybe i put it back wrong, but even i...

    steering box adjustment

    Hi guys On this subject i fitted new drag link and track rod for mot last week. I took them off, centered steering box (raised notch on outer back ring on box to mark on box) then refitted. I then had wheel alignment done. Steering wheel is just off center, so can i just adjust drag link...

    Overheating still..

    Hi all, Ok rad off and flushed. Looked pretty clean tbh, and water flowing well except for overflow. Clamped a hose on that and give it a flush. Now, all back and filled as suggested. The thing i noticed right away was jet of water coming from rad expansion outlet when revved! As i said this...

    Overheating still..

    All, thanks for the help so far, update this morning Before car started, coolant at right level, top hose normal, not collapsed or solid etc so all well to start. Absolutely no sign of oil in water or vice versa. No smell of exhust gases either. Took small radiator to tank hose off, some...

    Overheating still..

    Actually something else to note When running earlier with cap off, the pipe from rad to tank was at best tiny trickles into tank but also bubbles, certainly never a flow of water The pipe i replaced so is deffo clear. Should water flow from this or merely drip on occasion? This was when...

    Overheating still..

    Yes thanks, First on the to do list tomorrow Man i am so desperate to sort this, ive only joined the elite p38 club last sept since when ive only driven the darn thing for about 3 weeks before stripping her down! Im praying this is a rad, fan, cap, airlock issue. Any or all of them are...

    Overheating still..

    Well certainly today that was the case. But to be honest ive had her idling for long periods over last week in a bid to check all is well after head hasket job. I have a feeling if i let her idle here she will happily for ages. It think its when she hits the road, pressure rises and...

    Overheating still..

    Quick new info - ran it up the road a couple of miles, then let it idle for ten mins. No problems. Went back on road and twice over a couple miles the temp gauge just dropped from normal to zero (ie no temp) just for a second, maybe 2 max Now sitting ok again Would an airlock do that...

    Exhaust Manifold - Heat wrap instead of heat shield?

    Hi, Just working through what I need to reassemble after taking heads off, and one specific question. Can/Should I use heat wrap tape on the manifolds instead of trying to get heat shields? I really buggered mine up getting em off, and struggling to find any online - plus I'm thinking how...

    Heads off, advice on what next

    Im still a bit lost to be honest Can you explain a bit more detail on what i would need and need to do? Anything to test the block is sound seems a good idea, just want to do it right. As of now, i have the heads off, water pump off, but sump/front cover still on. If you can tell me briefly...

    Heads off, advice on what next

    Hi all, Finally got both heads off today (been away for a week or so) and so am now considering what parts to replace etc. The block looks ok, I can't seen any evidence of a slipped liner, assuming I should feel a ridge at top of any cyclinder (which I can't) Pics are here of the block and...
