when i take my valve covers off, is there any way to clean under there with some type of cleaner. thanks

 

Well, you could try some gunk or carb. cleaner and a wire brush. Or next time you go to the do-it-yourself car wash, bring them with you and use the degreaser and high-pressure spray on them. They might not like you when you leave though. Are you running a thermostat and a pcv?

yea, i got a pcv valve, and a thermostat in the upper radiator hose, why?

 

Oh just wondering why your taking them off for cleaning. No thermostat or pcv will cause a lot of sludge buildup.

Chris, what kind of oil have you been running in this engine ? The wrong oil will give you sludgey stuff under the valve covers, but it will be every where else as well. Maybe the whole engine needs to be cleaned ? DF

 

everything from mostly 10w 40, but i have put 10w 30 and 15w 40 to try to make the engine stop smokin.. didnt help much

 

20 litre bucket and a 500g of NaOH (caustic soda)
will take every thing off both sides

 

Liters, grams, what are those? Seriously, where do you get sodium hydroxide, Drano?

Barry

 

When you get it all cleaned off, don't use 10W-40 oil. See the "Oil and Lubrication" forum for a discussion on 10W-40 oil.

 

NaOH down here can be bought at Hardware and even Supermarkets

 

CJR900, what I was wondering is what brand of oil are you useing ? I don't think the weight really matters much. There are some brands of engine oil , however, that have a lot of wax in them. You should avoid them if at all possible. DF

 

im running some cheap kinda from the dollar store right now.. like 75cents per quart. i usually dont put that in.. but it burns it so fast i really didnt think it would matter

 

Blow-by is the problem, rebuild is the answer. In the meantime run straight 40W.
