no exhaust gases in coolant

pressure testing confirms no issues on that score either

time to hand it over to someone for some no doubt hideously expensive investigations

Look on the bright side Ade. No leaks and gases escaping via dubious gaskets and no cracked heads.......

Otherwise you would be looking at high Zoot ally heads and a Holley fuel injection system to massage out that extra 75-100 BHP

Try restricting the coolent flow as in the go jeep link I posted. You just need a piece of ptfe chopping board. Cheap test before you go spending

Still got the bling grill on or std?

donk498 · « **Reply #260 on:** September 29, 2014, 08:35:24 PM »

Can't remember if we covered this before, but it wouldn't be running to lean at high road speed due to airflow thats causing it?
Bonnet vents causing ram air to filter?

Bulldog67 · « **Reply #261 on:** September 29, 2014, 08:49:06 PM »

Carb is sooty if anything so that would be too rich?

Admittedly old engine but vents were put in coz of overheating and they are faced to let heat out

Grill is a stock option

wildwood · « **Reply #262 on:** September 29, 2014, 08:56:13 PM »

Sure I mentioned this before back in the dark ages but......has your dizzy got a vacuum advance and if so is the tube perforated so air escapes.......

Had a BMW once that had that PROB so at speed it was too advanced and ran hot......... And then the head gasket went......
Head gasket replaced and new rubber advance retard vacuum hose and PROB solved....

Just another thing for you to check

Bulldog67 · « **Reply #263 on:** September 29, 2014, 09:08:11 PM »

keep them all coming - I can at least provide the lucky mechanic a list to check

im having trouble financially committing to this all over again tho

demonicwillow · « **Reply #264 on:** September 29, 2014, 10:57:54 PM »

What pressure is the radiator cap ?? If that is faulty or not rated high enough, that may cause issues, if the cooling system isnt pressurised enough the coolant wont do its job properly and maybe prematurely boiling off ... Just a thought.

Bulldog67 · « **Reply #265 on:** September 30, 2014, 06:56:02 AM »

Sorry my bad - new rad cap from FSJ specialist & new bottom hose

JamesH · « **Reply #266 on:** September 30, 2014, 07:09:43 AM »

Has anyone given the rad a really good check over? If it was filled with mud once then I would remove it, soak and meticulously clean. It's free apart from time.

Got to say, with the ZJ, it took Kev thoroughly cleaning the radiator then me again before it was clear enough not to over heat.

Brynjaminjones · « **Reply #269 on:** September 30, 2014, 08:49:54 AM »

At what kind of speed was your ZJ getting hot Jay?

jay140285 · « **Reply #270 on:** September 30, 2014, 09:10:03 AM »

55 and above mainly. Pottering about it was ok

Ah okay - I was just interested to see how a dirty rad affected it, as mine runs hotter than it used to at low speeds these days.

Bulldog67 · « **Reply #272 on:** October 01, 2014, 09:26:14 PM »

what are the thoughts on a new rad - if I buy a fancy pants 3 core aluminium job shall i get one for an auto or shall I get a manual one and fit the after-market separate trans cooler?

Nosebolt · « **Reply #273 on:** October 01, 2014, 09:38:38 PM »

did you ever try shielding the gap between the front valance and sump?

Bulldog67 · « **Reply #274 on:** October 01, 2014, 09:43:03 PM »

yes but couldnt get anything to fit solidly - obviously that is me being a tard and will bite the bullet on that and get someone to fabricate one that can double up as a sump guard
