Need lots of advice.

Hello everyone,

I just purchased a 1998 Eclipse GS-T. I test drove the car about a week and a half ago and went back and picked it up last Tuesday. The car drove fine on the test drive and after I actually purchased it has gone down hill fast. Let me go over all the issues. I would really like some feedback..


PROBLEM AT HAND

First. The engine is making a loud ticking noise. At first I thought it was a broken piston arm but a few people ( who have more knowledge than I ) said it was probably bad lifters. I did a compression check and everything came of fairly even. So I am leaning more towards it being lifter tick. Along with the ticking noise the engines performance is extremely poor. The car has absolutely no power. It is burning oil because every now and then it will poor white smoke out the exhaust. Sometimes though it runs just fine. I changed the oil and added in some Lucas and the ticking stopped until earlier today. It ran good for about 150 miles. Also I just installed a short shifter which functioned just fine. Then today on my ride home from work when ever I try to shift into third it feels like the gear locks in and as soon as I come off the clutch it makes a grinding noise and kicks the stick out of gear. Also I reset the trip meter and now it nor the odometer is reading mileage. The car also has a very slight oil leak which seems to becoming from around the turbo. Also when the car goes from relatively high RPMs ( 3-5k ) and i put it in neutral it idles down so low that it cuts off..


WHAT I'VE DONE
Today I took it by a local shop who deals with DSMs and other performance cars. We did some checking and this is what I know. The BOV ( which is a POS OEM 2g ) is no longer functioning properly. It is actually sucking in air. After we disconnect the BOV hose that runs to the turbo we wanted to check and see if the turbo was functioning. That all appeared fine. But after high RPMs there was a little white smoking coming from the piping leading to the turbo. I am looking into getting a new BOV and possibly a rebuild kit for my turbo. That was the recommendation of the mechanic. They told me the reason the car is cutting off is because the BOV is sucking in air instead of blowing it out and that is messing with the mass air flow sensor.


I think that is mostly the symptoms I just really need to diagnose the problem. I am new to DSMs and forced induction vehicles all together. And help would be greatly appreciated. I left some info about the vehicle below in case it is necessary.

YEAR : 1998
MODEL : Eclipse GS-T
MILEAGE : 78,000
TURBO : 16G
OIL : 5-20 Synthetic
ENGINE MODS : None


If there is any information I left out that may help anyone please ask. Like I said. I'm a scrub. Thanks in advance



P.S - I AM UNABLE TO RETURN THE VEHICLE as I am sure someone will suggest.

It does not look like it is a 6 bolt motor. It looks like sombody just dumped alot of problems on you. Read alot and slowly make things right with the car. They are alot of fun but alot of work.

turbo should have no play at all so if there is alot in every direction then that is the source of your problems....seems to me the previous owner blew the turbo and took the car for a trade in.....its a relatively low mile car so odds are your not that bad off....looks pretty good as well....so get your feet wet and swap that turbo yourself or take it to that shop you get cheap work from and go from there...my guess is you will be a relatively happy camper afterwards.

The reason I said it looked like a 6-BOLT is because the intake manifold and CAS looks like its from a 6-bolt. But like I said, I could be wrong.

6-bolt intake manifolds do not have the spot on top for the map sensor as they were built into the maf on the 6-bolts. Take the time to learn how to change a turbo and do it yourself to save some money. It is really not a bad job, even if it is your first time.

Yea I am in the process of it now. I've removed the J-Pipe and some of radiator tubing thats in the way. Disconnected the wastegate as well as removed the heat shield from the headers. Is there a simple way from here to remove just the turbo while leave the exhaust manifold? I am going to pick up the new turbo tomorrow.

just unbolt the 02 housing and the top four bolts holding the turbo to the manifold along with the oil and water lines running to the turbo and you should be good to go.just drop it out of the bottom of the front end
