DaveT Posted March 10, 2022 Share Posted March 10, 2022 Need more info... Was it run and driven often? Was it sitting for years? Carburetor? Quote Link to comment Share on other sites More sharing options...
el_freddo Posted March 10, 2022 Share Posted March 10, 2022 I’d say the catalytic converter is breaking down. Won’t have much to do with high oil pressure. Can you get it up to a certain rev “limit” through beach gear with about the same amount of load on the engine? If so, collapsed cat converter is my bet!

Ladyofdoom Posted March 10, 2022 Author Share Posted March 10, 2022 I removed both cats hollowed them out but pending putting exhaust pipe back on but I was just under the hood to check out carburetor and seen this IMG_0327.HEIC Quote Link to comment Share on other sites More sharing options...

I’m not to sure of that but it only has 90000 miles and is still all original and in great condition and it had current registration so Quote Link to comment Share on other sites More sharing options...
Steptoe's photos Posted March 12, 2022 Share Posted March 12, 2022 1985 would be carburettor in any world except turbo and XT ? 90,000 is very low, suggests not driven much somewhere in it's life time. Anything else you have done and not told us, like the cat gutting ? So many things to cast a wand over, such as fuel quality, age, volume. Just replacing fuel filter(s) can resolve issues, so too a fuel cleaner. How is air filter ? If it is copping oil and water mix from blown HG and or blow by, it may not flow well. I always say to start with a compression test and come back with those findings Quote Link to comment Share on other sites More sharing options...
