Just wondering but does anyone know a way of doing an engine flush. I suspect one of my hydraulic lifters being bad. Clogged somewhere along the way. Is there a good way to flush the whole engine out and clean all of the engine sludge out., I am just trying to get rid of my damn ticking noise which annoys the crap out of me.

If this does not work can I remove the lifters without removing the intake manifold? I really don't want to be removing half the engine for something I can maybe live with lol.

 

if you have sludge build up and you run an engine flush solvent through it, some big chunk of crap could break loose and clog the oil pump or get stuck somewhere and wreak even more havoc. I would try changing the oil with good quality oil. Try Castrol GTX high mileage 5w30. and a good oil filter (fram sucks!) Substitute one quart of oil for one quart of Lucas oil stabilizer. so if it take 5 qts of oil then use 4 qts and one qt of Lucas oil. If the noise does not go away, either the lifters are worse than I thought or something else is rattling.

If the lifters are bad, changing the oil often with good oil is just going to prolong the inevitable and sooner or later they will need to be replaced. And yes you probably will have to remove the intake manifold to replace the lifters.

 

Depending on the number of miles on your engine, I have always been told not to run an engine oil flush because the sludge fills in the greater tolerences caused by wear (this was in the days of strait 40w or even strait 50w). If you have high milage you can try a higher weight oil. I second the worry of clogging the oil pump.

 

the best way to flush an old engine is to drain the old oil, and pour in 4 quarts of auto trans fluid and i quart motor oil and drive it around town for about 10-15 miles go back home drain and change the oil and filter, transmission fluid is very similar to 5w-30 motor oil except it has 3x the detergents i used to work at a gm dealer in the service department and any car that came in all sludged up or with a blown intake (inside the motor looks like peanut butter) we would flush it out with fresh tranny fluid. i just did it on my 93 caravan winter beater with 151,000 miles and a lazy lifter fixed the problem like it was never even there

 

Thanks guys, I think I will try running heavier oil first.
The noise has gone away at time, completely than it came back once the vehicle was warm. The truck only has 125k miles. But last time the noise went away it was sitting for a few days a little bit cooler morning started up the noise wasn't there! So 5w30 versus 10w30 be a good idea? For the last week or two I have had about 1.5 liters of tranny oil in the engine so far.. hasen't done anything yet. But I might try 5 speed's idea.

 

finnaly some one knows what tranny fluid does for an engine. do this

 

LOL.

 

Be careful with the tranny fluid. I have done this many times before, but only let the engine run for about 1-3 minutes. Any longer than that and you can start to leak through seals.

 

its a OK idea...but causes as many problems as it solves there is the sawdust trick too...used to sell cars, done it all

 

Sawdust? Trick what do you mean?
