ENGINE SLUDGE CURE (please CAR help)?

Question

Hi My 2001 Camry stopped picking u speed from a standstill, and also blows out a lot of smoke when initialy started. MANY PEOPLE HAVE TOLD ME THAT IT IS DUE TO ENGINE SLUDGE IN THE ENGINE!!!

NOW MY QUESTION:

HOW DOES ONE EITER REMOVE OR CLEAN ENGINE SLUDGE???

THANKS 4 YOUR REPLIES AND HAVE A GREAT SUNDAY !!

Answer 1

when the four or six cyls start doing that it can be sludge or your valve guides are getting warn out.. This is what you do. take it to a dealer, do a maintance. Timing belt, valve cover gasket, etc. tell them what is doing, and they have the stuff to do it with. there is over the counter stuff you can buy to do it your self. older cars are ok, like the old 69 camaro. these newer cars if it is one that you want to keep, then fix it, but it is going to be spendy.. but at least it will be done right.

Answer 2

Sometimes smoking engine exhaust at start up is caused by engine oil seeping into the combustion chamber through the top part of the engine. oil is pumped up from the sump or crankcase to the valve train on top of the engine. The oil often seeps down into the combustion chamber through worn valve guides and mixes with the fuel, when the spark plug fires it ignites the mixture of gas and engine oil creating the oil you see at the tailpipe.
In some cases the small canals in the cylinder head become clogged with sludge, oil pressure builds up and the oil cannot return to the crankcase and is forced down thru the valve guides into the upper cylinders and mixes with the fuel causing the smoke you see. A good honest mechanic can tell you if the piston rings may also be worn.
But my guess is, oily smoke seen upon acceleration after an idle cycle usually comes from the upper end (cylinder head).
In answer to the removal of oil sludge, you can try to open the valve cover to see if it is impacted with sludge and if so try to clean it out (USE LATEX GLOVES TO PROTECT YOUR HANDS), you probably will have to replace the valve cover gasket, then try an auto parts store to recommend a good sludge removal product. Also your spark plugs may be full of oily carbon causing poor acceleration and probably should be replaced along with a fresh oil change.
Alll this can be done by the average person with some basic knowledge of engine mechanics in a few hours. If this repair works change the oil after the next 1000 miles.
Good luck.

I haven't heard of sludge in an engine in 50 years. The modern oil filter and improved oil has done away with it. You don't say what color the smoke is and these mekanics that pretend to know something don't ask. White smoke means coolant in combustion chamber. This is an indication of possible leaking head gasket or intake manifold gasket. This could also explain the power loss somewhat. If it is blue smoke it indicates oil in the combustion chamber. Possible worn valve guides. If it has been burning oil for an extended period it could have damaged the catalytic converter. This would alsoresult in a power loss. now you have some clues to follow up and find the problem. It is not sludge.

I don't think it is a problem with sludge. Black smoke at starting usually means oil is getting into the cylinder. Usually happens if you park your car for long time under sun beating on it. The rubber valve oil seals crack and leaks oil into engine cylinders.

Most experienced mechanic can service the valve oils seals without removing the head. You can shove a compressed air to spark plug hole to keep the valve up, then use over head valve spring compressor to take the valve out, replace the oil seal, and reinstall the valve.

Answer 5

Pull off the valve cover clean it out and carefully scrape off the grey / brown / black crap from the top of the cylinder head and valve cover. What usually happens is the oil return holes on top of the cylinder head becomes narrowed or plugged completely closed preventing the oil from returning to the oil pan. Oil can actually dam up on top of the motor where vacuum sucks oil down the valve guides causing smoking.

For some unknown reason Toyota insists on using 180 degree thermostats. The motors don't get hot enough to drive off moisture and condensation. Gum and varnish build up quickly especially when lazy people don't change their oil.

Resssemble the motor and add a can of Rislone instead of one of the quarts of regular oil. It's a very high detergent motor oil replacement that disolves gum and varnish. Drive the car 2 - 3,000 miles. Before draining the oil add a can of engine flush and let the motor idol for half an hour before draining. Do the same steps as above every 2 - 3,000 miles for the next 10,000 miles.
After that time be more religious about oil changes. That's exactly why your motor is in the shape it is. Get it changed every 3,000 miles come hell or high water.

Answer 6

It sounds like you have worn valve guides and the valve seals are leaking. You are probably have several valves that aren't sealing do to the oil leaking through the guides and building fried oil in the seats and on the head of the valves. if you ran a carbon cleaner through this engine it would probably leak oil worse as the seals would leak more and the rings would probably collapse letting oil blow right past them. you may be better off having it checked by a good mechanic to see if you have anything worth repairing.

Answer 7

To remove sludge from the motor first get oil, oil filter, and engine flush. Engine Flush is the name of the cleaner. Follow the direction on the back of the bottle. Replace one qt of oil with Lucus oil treatment. This will help lube your bearing and pistons, improve compression, etc. Good luck!

Answer 8

I have never heard of sludge causing an engine to blow smoke, rather it is burning oil. If you are loosing pick up it could be that the plug are fouling because the oil is slipping past the rings and burning in the cylinders. This also means that you may also be loosing compression too again causing loss of pick up.
