Re: Fx45 Burning excessive oil
I've read many of these Forums, and recently I came across one that a guy teared down the FX45 engine apart to rebuild it. The engine had 320K and nothing was wrong with the valve seals, cylinder wall nor the rings were worn down. The problem with these engines is that they are very sensitive and if you dont use proper oil and gas with proper maintenance the pistons very easily builds up carbon! Once the rings build up a little bit of carbon they stick very easily, and lets of coarse oil to go by and burn! I have a '03 FX45 with 195K, It started to burn lots of oil not too long ago. What I just recently have done is took out the plugs, SOAKED the plug holes with SeaFoam ''DEEP CREEP". I used 2 cans, 1 for each bank equally and left it over night. This method will clean the whole piston from the top and going thru the rings. The next day I pulled out the Injector fuse and cranked it couple of times to let out most of the fluids. I then started it with new plugs of coarse and let it run for about 15 mins to burn off all the CRAP out (Start it outside as there will be LOTS of SMOKE!) Then drove it for about 20-30 mins until there wasnt anymore smoke as well as to let the sludge end up in the oil pan. Came back to the shop and changed the oil and added one full can of (1 Pint) SeaFoam with synthetic oil, to do bottom end cleaning! I'm going to now change the oil every 3K with 1 Pint of SeaFoam for about 3-4 times to make sure all the carbon gets cleaned!
I've been driving it for about 2 days now after doing that and the engine has showed lots of good results so far! More Power, more gas efficient and dont notice anymore blue smoke! I will keep u guys posted after 500-1000k to see if the oil level has gone down or not! Lets all cross our fingers this will work so we dont have to spend thousands on an engine rebuild!
