I hope the engine strip and rebuild doesn’t fight you like the rest has seemed to do 😊. Good luck 👍

She is a little, but I’ll win 😂

Not sure what service data you are referring to however the Honda service manual does not tell you to remove any covers, or bolted equipment of the engine to remove it.

[@memybikeni9931]

Depends what your source of information is, and as I have alluded to, i haven’t found it necessary.

Perhaps , I know a little late , use a freeing oil , Triflow is extremely good , if there is enough meat on those screws , and being cheap , you can sometimes get Gland Pliers , [ channel locks ] on them . Not trying to teach you how to suck Eggs .......Fight the Good Fight . . Good Luck .

Yeah I threw heat and all sorts, but they weren’t having it. I now have to drill them out as the engine is still apart on my bench. I’m just considering on exactly how to repair.

[@brentbauer8258]

If your cams last longer than 30000km you did not get a defective cam. My 1985 is at 60000km with no oil or am issues. My 1983 had 57000km with no cam or oil issues. I think the person used gloss black plastic dip paint…

[@memybikeni9931]

Yep, the cams don’t look too bad actually having pulled the engine apart. Regarding the paint it did smell like wood gloss, when I managed to get the engine running it just bubbled up. I am going to be replacing the crank cases, but have already stripped the terrible paint of most of the rest of the side cases and rocker covers etc. getting there slowly.

Cams not getting enough oil is a fallacy

[@memybikeni9931]

Source ?

[@barrythatcher9349]

The previous owner must have painted the engine with gloss house paint. Just terrible stuff.

[@memybikeni9931]

Yes i think it was and I’m not joking, it stank like wood gloss. I have completely stripped the rocker covers, side cases and heads of paint, and I’m am replacing the crank cases, which I need to tidy up, and then it will all get repainted in VHT Black, with the side cases left aluminium with some Honda Racing colours thrown in. Just finishing the clean up, and waiting on parts for the re assembly. Hoping it looks nice, and the main thing, hoping the rebuild fixes the main problem being it had low compression in number 2 cylinder, water in the crank case, and white smoke. Once I’m happy it’s all fine the body work will need attention, not to mention the forks and brakes. Big job…

[@barrythatcher9349]

@@memybikeni9931 keep up the good work and I hope you can get the compression issue in the number 2 cylinder fixed. That is going to be the hurdle.

[@memybikeni9931]

@@barrythatcher9349 the head gasket looked in very bad shape, it wasn’t able to be removed in one piece so probably where the issue lay. Water in the crank case and compression issue, almost certainly the head gasket. It wasn’t extremely low, but relative compression was 20psi difference, and fluids in the crank case says it all.
