cliff.b Posted May 21, 2023 Report Share Posted May 21, 2023 Out attending a classic car event and car was running nicely then, on entering the parking area seemed to be running on 3 cylinders and lots of smoke from exhaust. Found plug 4 was oily and smoke from plug hole. Replaced plugs, restarted engine and now running fine. Would welcome any thoughts on this? Link to comment Share on other sites More sharing options...

Pleased it was a simple fix at any rate. Link to comment Share on other sites More sharing options...
dougbgt6 Posted May 21, 2023 Report Share Posted May 21, 2023 Yes dodgy plug or loss of spark, I've one of these, a couple off quid on Flea Bay. An easy test when you've got no tools. Doug Link to comment Share on other sites More sharing options...
cliff.b Posted May 21, 2023 Author Report Share Posted May 21, 2023 Things have moved on. The problem re-occurred and realised the smoke is white and a lot of my coolant is in the expansion tank. Started with rad cap off and when I revved the engine, coolant erupted out if it. Seemed to run ok on the way home but did a compression test and cylinder 4 is a little lower but steam coming out of radiator on each compression and steam out of plug hole when tester removed. I'm presuming head gasket 😒 Link to comment Share on other sites More sharing options...

Iain T Posted May 21, 2023 Report Share Posted May 21, 2023 (edited) How is the oil? Do you see any water or emulsion on the dipstick? I think you are correct to suspect the head gasket. Iain Edited May 21, 2023 by Iain T Link to comment Share on other sites More sharing options...

I think you are correct to suspect the head gasket. Iain The oil looks fine and no increase in oil level. Engine appears to run as normal when driving and temp not increasing. Only seeing the symptoms at tickover or at low engine speed. I emptied the expansion bottle back into the rad and it was almost full again so not really losing much coolant, just pushing it into the bottle. Any recommendations for head gasket supplier. Spit 1500. Link to comment Share on other sites More sharing options...

I'm not the best person to advise as I didn't really have a problem with mine. I would assume Canley, Paddocks to be the natural suppliers.

Looks like there is only one type of head gaskets for the 1500 but suppliers prices seem to vary quite a lot. No idea if that reflects quality or if they all come from the same manufacturer.
