Think my engine may be goosed!

Thats what I did before going over to electric pump. Have a word with Tim/Jimmys, got mine of a goosed rad. You could have had mine but I used it on my home made swirl pot.

Doh, sorry wrong sign in, it\'s FD3UK

Be careful mate - as a lot of the others have said it does sound like it could be the Water Seals.  Mine had these exact symptoms and turned out to be the seals.  What ever you do dont let it overheat like I did - the bill goes through the roof.

One thing that mine did that seemed to point towards the waterseals was this:   On tick over CAREFULLY remove the filler cap.  Leave it running and if it starts spurting out with some force its pointing towards the seals.  Mine had these AST Issues - I replaced the cap and it seemed at the time to improve things - it soon went all wrong though.  I think maybe when the seals go it pressures up or something and puts strain on the AST - pipe, caps, joins etc.  Im no mechanic so I could be talking complete bull - this is just how it happened to me.

Hope im wrong though - fingers crossed

Yeah, i think it\'s very possible you could be right that the water seals have gone. I am going to get it pressure tested when i can. Then i\'ll have a fuller picture of the state of play it\'s in.

Don\'t eliminate the ast, it is there for a good reason..to stop the tiny air bubbles eroding the engine internals. Get an ally one. Also do the fan switch mod so you can overide the cooling fans in traffic or hot weather.  I reckon a pressure test would finish off the seals altogether if they are going..try the rad weld trick found on rx7club.com before spending thousands rebuilding.

The air bubbles created through cavitation (Yup, i\'ve done my homework!) are created mainly through heat - hence why the RX-7 has them, but not other cars. If you can guarentee that the coolant will remain cool enough (Temp of fans coming on being lowered for starters) then it is something that can be done with safety.
