Bought an engine from a company about a month 1/2 ago that came with a warranty to not knock, smoke or burn excessive oil. Well I got it up and running. Motor runs great and hasn't given me any mechanical problems. Said they did a leakdown test on it and it read 10's all the way across. Never had a compression test done but i'm sure it's within oem range. So far i've only put 121 miles on the motor which according to the paperwork my reciept read means the motor has a total of 119,377 miles on it. Did an oil change on it when the motor was out of the car with mobil1 10-30 and I checked it today to make sure the oil level was still where it should be. Well it was down to the 1st notch on the dipstick. I checked it about 4 times to make sure i wasn't seeing things. What could make the car burn that much oil in 100 miles? I don't notice it smoking when I drive and can't smell anything burning.

On another note I failed my emmissions test because I had a high input coolant temp sensor problem which I fixed and now it has a cylinder 1 and 2 misfire. It smells like it might have an exhaust leak and I can hear it underneath the car. Sounds like it's coming from where it connects to the cat. Would this cause a cylinder misfire due to back pressure or something else. Has new spark plugs and wires if that means anything.

Thanks HT

 

bump back up ttt

 

IT MAY BE YOUR PISTONS RINGS ARE WORN OUT OR U HAVE A LEAK PROMBLEM CHECK THE ENGINE U NEED TO GO UPCLOSE AND PERSONAL WITH IT..

 

fill it back to the proper oil level and see if it changes in the next 100 miles?... do you have any leaks?

 

im with ^^. check for oil leaks. its possible your burning it off but you would see blue smoke if you burned up a quart in under a few hundred miles. i believe you have a leak...possibly your main oil seals on your oil pump or in the tranny. check your cam seals by the timing gears too - they tend to leak if theyre cheap or rtv silicone isnt used. ive heard of aftermarket distributors also causing alot of oil to burn off as well too...but i dont think thats your problem. let us know whats up

 

First-Thanks for all the help and the replys. Just a little update on the emissions deal; I bought new spark plug wires which didn't fix the problem-however after I did some researching on h-t about single cylinder misfires I came to the conclusion that i might need some intake/carb cleaner. Bought some yesterday for 2 and some change sprayed out the intake manifold w/the car running and sprayed it through the brake booster vac line. Tons of smoke came out...drove it for awhile and passed with ease today.

- There is slight oil coming from the exhaust side cam cap so that will be getting replaced this week. And in the coming weeks I will have the timing belt, water and oil pump changed.

Thank you again stickielegs, vietnamezerice and hollums!

 

cool good to know you got that taken care of. make sure you silicone that cam seal inside the cam journal and inside the cam cap so it makes a proper seal. good luck
