Cheers Jon. Sio in short, it needs to bled from 3 points and needs to have the Pink OAT coolant in it? Where are the 3 points out of interest?
1. to the right of the air filter on the over gearbox pipe 8mm bolt
2. right hand side of the rad as you look in, flat screw head or 13mm
3. behind the plastic panel where the clutch fluid top up is, about 6" to the right of it on the bulk head its an 8mm, it comes through the bulk head from the heater matrix

So being really thick here but if they open up all the bleed points, drain the coolant, tighten the bleed points up again and then put the new coolant in, everything should be fine?

Noooo :)

to full drain it you really want the radiator pipes off, removing the bleed screws will make it come out quicker though

When re-filling have all of them tight, fill as much as you can, then open one at a time to let air out, once coolant comes through with no air tighten it up and go to the next bleed point, keep checking you have plenty of coolant in the bottle as you bleed each point

run the engine and bleed it again

Cheers Jon.

I'll pass this info on to the garage. Taking it in on Wednesday to get the Idle Air Control valve issue sorted so i'll ask them to do this at the same time.

Out of interest, How far are you from Newcastle Upon Tyne. Live litterally just off the A1. For future reference lol.

My 2000 vvc is on its original gasket and apparently the one with the plastic dowels. It has covered just 28k mind!

The more I look into this engine the more I am of the opinion that although the HG isn't the most robust it is the components around it (cap, rusting pipes, inlet manifold gaskets, inoperative fans) that fail first taking the gasket past the point of no return in it getting too hot!

The one thing outside of this is the thermal shock theory. What I am doing is taking some advice from one of you on here (sorry can't remember who!) and not taking car abover 3,000rpm until the oil temp is reading over 90oc.

So far so good and in combination with a low water alarm and soon some new stainless pipes & radiator I am hoping to keep going on the original gasket a while longer!!

watch me eat my words and call upon one of you trusty mechanics at 30k!!

Might of been my words..lol I can remember writing it so many times

But the one thing I will say is, if it ain't broke don't fix it...lol

I did one in london a few month back a 1996 F still had its original gasket and in use every day

Peter,

When I got my MGF the fact that it had a recently replaced head gasket was one of the things that made me decide it was the one for me, I'd heard so many horror stories about HGF and one of my friends had a very early F which had HGF early in it's life but outside the warranty.

The more I found out the less I worried about it and when I pranged the F and replaced it with a TF I was quite happy buying one without any history as everything looked good and I knew that there were people out there who could deal with the worst at a sensible price.

My 2002 TF had been losing an increasing amount of coolant all year, but it started to get worse over the last few weeks, oddly only on short runs, it never lost a drop on a long run. Russell Walsh was booked to come and look at it and after he pressurised the cooling system we saw the oil level rise - the dreaded HGF! My response was almost 'so what, we'd better get on with it' as it's not the disaster everyone tells you it is. When the old gasket came off, there it was, a tiny area of the sealant on the gasket lifting, probably leaking only as the engine heated up or cooled down, hence the lack of loss on long runs.

Just a couple of hours later Russell was on his way and everything is now fine with the car, just my pocket is £320 lighter!

HGF in most cases will cost you about the same as a cam belt change service at a main dealer if you get one of the mobile mechanics on here to do it for you, it's not the worry all the 'experts' at the garages will tell you.

Anyway - don't trust garages who don't work on K series engines regularly, my local garage wanted £650 to replace the HG on my son's Rover 200 1.1 after my wife took it in while I was away from home. When I got home I diagnosed it as a leaking coolant cap - £5 to fix!

I think I need my head gasket sorted on my mg tf paid to have the water pump fixed a lil while ago cause was leaking had my car back a month or too and now I got the dreaded cream/white colour in my oil and losing coolant slowly but garages are quoting ridicoulous prices I’ve seen comments of people getting ther car perfectly fixed for like £320/400 on here any help?

You don't say what part of the country you are in, but a couple of mobile mechanocs who specialise in the K series and are well regarded on the forum are:

Russell Walsh - Mg Rover Solutions in Kent

Dave and Kayleigh Allkins - MG-Rover Mobile Mechanics in Derby

Jon Norris - Roughluck Racing in Hull

Each of the above will travel pretty much anywhere in the country for the cost of fuel in addition to the repair.

hi Ben

i also live in herne bay and after i bought my mgf 18 months ago that had had the head gasket done previously but i then had overheating issues randomly for next 12 months before thanks to covid i replaced the head gasket myself as i had the time and the car wasnt being used. i went thru all the diagnostics with members on here, sniff test didnt show head gasket and when i did finally work on the mgf the MLS head gasket was shot to bits ,anyway a chap on the train i used to see at herne bay has a gold mgf and told me there is a specialist ex mg rover mechanic down sea street near sunnyhill road and the new ballet school, might be worth checking with them.
thanks
martin

What happened to cause this failure?
how long do you have? :) . bought the car with head gasket done previously (it was replaced under3 years ago when bought but had only done about 500 miles in those 3 years), drove it home on one of the hottest days of the year no problem, next day took it out just around town for about 3 miles and it overheated so started to investigate, changed thermostat to 82c degrees one but then noticed no return to the header tank so then i took the distributor end jiggle valve apart and it was clogged completely right to the top of the valve that i had to use screw driver to dig out this pink paper stuff below, so it probably had air locks all over the place which probably caused the hgf. was losing water about 1inch per month, some months it was driving fine other times it would overheat, did sniff test showed nothing, spent alot of time on here listening to peoples advice, no mayo, no smoke just a little bit of water loss and the unreliability of whether it would over heat. in the end replaced mls gasket with new one but then had overpressurising start to occur within 300 miles of the new gasket (head was skimmed as well), so after advice from here i learnt i hadnt done my homework and should have put payen gasket on as i knew about liner height but thought mine were high enough for mls when it wasnt. so its been fine since i put payen gasket on it. live and learn as we say :)

Thanks mhack. Some really relevant info shared there.
I wonder if that pink stuff is one of the many forms of leak-sealant compound?
I share some of your pain. I've had to flush out coppery deposits, clear out the IM jiggle crud, replace that broken gasket and buy a new rad for a previous TF - and wasn't best pleased with one of my previous owners...)
