I want to clean my cylinder head and also get the carbon build up off my piston heads which is the best way to go about getting it off. | ||

With the cyl head I suggest breaking it down. Remove the valves, springs, spring retainers etc. No need to remove the valve seats unless you plan on replacing them. Get some valve grinding paste and a suction cup tool and reseat the valves when you put it back together. On the head I use a die grinder with a 3m schrub pad attached. You could also use a drill with the same attachment. Clean the head until the metal surface between the head and the block to shiney medal. Be sure to use compressed air to clean out every groove and cranny on the head. On the pistons stuff rags in all openings except the pistons. Smear a light coat of grease around the outter edges of 2 pistons. Turn the engine with the hand crank until the 2 greased pistons are near the top. With a scrapper or again with the 3m pad clean the carbon off. The grease keeps carbon from falling into the pston wall which of course is very bad. After cleaning two pistons turn the engine to drop the clean pistons and wipe the grease away. Block the clean pistons with tape or rags and do the same process with the 2 dirty pistons. I think the Haynes manual list these steps. It is important to not allow carbon to enter the piston walls. I also use a shop vac to suck the scrapped carbon away. Please let me know if you need additional information. I am always available. If you are near by come on over. Stephen | ||

Hey, this may sound rediculous...but is steam cleaning a Rover engine out of the question? What measures should be taken to prevent water entrance on water/moisture-sensitive parts? EY | ||

On modern rovers, the carbon buildup gets so bad inside the combustion chambers/valves that the cyl. heads have to be removed and the carbon has to be taken off manually. Now first off Brad, you need to adjust your carb to prevent this. It won't do you any good if you clean all of the carbon off and then go and do it again. But that is a totally different subject... You might want to try some "cheap" engine cleaners first. I know many people recommend this stuff called "Sea Foam" that is sold at NAPA which might help knock off the carbon. For less than 5 bucks, it is probably worth a shot. It might make a difference! You might want to look into a professional engine flush. I've heard those are pretty good and remove ALL of crap from your engine. But it might be more trouble/too expensive to do but it is an option. You can pull the cyl head. There is about 5 hours of work there but if your climate is like mine, its way too cold to go do any of that stuff outside, hehehehe. Max T. | ||

There was a big discussion about Sea Foam on the MG board that I frequent and the general concensious was that it makes a huge difference. I ran a can through my MGB engine and it seemed to smooth out the idle and just generally make the car run a little smoother. I would highly suggest trying it, just make sure you're in a well ventillated area because man will it smoke. | ||

The cylinder head is already off. I took it to work and used there parts cleaner and that took all the stuff on the outside off. now I just need to get inside the intake and exhaust chambers. |
