My engine's F***ed

[97grandamGT]

I uh... took a corner too fast and sloshed all the oil to the side of the pan (at 4500 rpm, mind you) starving my engine of oil and now my twin cam sounds like two jackhammers having rough interactions, KNAAAMEEAN? Anyone know where i can get a used engine (with under 70000 miles preferably) around ohio? Or, I know its a little far fetched, but anyone willing to rebuild my engine for less than $900? Im a college student and need transportation!!! :banghead:

I didn't think that was possable. Or atleast I never thought about it before. I ran i-70 speedway lastyear with my quad and never had a problem like that. I-70 is a 32 degree banked, halfmile track. I took the corners at around 90 mph, at alot more than 4500 rpm and never had a problem. I ran valvoline 20w50 racing oil. Is this something I need to wory about myself.

[Lash]

LD9's have a crappy oiling system. More than likely you were low on oil too which makes matters worse. So....was it the #3 bearing that spun or what?

[FAST 90]

Is there and aftermarket pan, or oil system that a person could get to keep the quad better oiled under excessive cornering?

[urweak]

talk to thewhiteknight, he might have some twin cams on his hands. he right around the west virgina, ohio, pa boarder

Mine is ticking sort of like that as well, I really hope it isnt a bearing! that would be crap... my tick/ratling noise is coming from the intake camshaft area, though -- and it increases as the engine speed increases... I still havent disassembled my engine to figure this one out, any ideas before I rip the top end of my LD9 apart?

[darkfox]

how loud is it?

i think a very, very light tapping is normal for the engine. It could just be valvetrain noise on an older engine.

any louder and you could have an issue...

[TheFence]

it was just a little ticking, then it escalated. now its more of a clanking. but now it is also random, it doesnt keep pace with the engine, it sounds more like a quarter being tossed around inside the camshaft. needless to say, I dont drive that car anymore, until its fixed.

check to see if the noise is coming from around the timing chain or by the cam towers...

The damn #3 bearing, my car lost oil pressure on friday, and say good bye to the #3 bearing. There is not much left if it now, the crank is junk (or least needs to be turned down), and the rod is toasted.

[darkfox]

it just lost oil pressure?

[Scorpio6t9]

Well i assumed it lost oil pressure, the oil was just changed about a 3 weeks ago and the engine does not burn or leak oil. So the pan was still full, so i assume i lost pressure. I havent pulled apart the balance shafts yet, to see if its junk.

Similar situation here. I took my car to pepboys and when I drove there thing ran great. With under 50,000 miles on it it probably should. When they got done and I drove it out first thing I noticed was lack of power followed by knocking in the motor 1/4 mile later.
My motor is junk. At this point it's my belief that they ran it with no oil in the car or possibly low oil level and then filled it after the damage was already done.
I would love to find more info on the lubrication system used in these motors that I see 2 post stating are bad designs. One here and one on grandamgt.com forums.

[darkfox]

i would like to see some investigation into this myself.

i have 164,000 miles on my rig and have never had such problems.

[Scorpio6t9]

I have 160K+ on mine before I had a problem, not all that bad of a thing. I wanted to built that motor anyways!!!!!

[D0M1N8R]

If anyone knows more info as far as this issue goes please do let me know. Looks like I'm about the enter a legal battle with pepboys and any information I can get as to how they may have wrecked my motor would be great.
Could they have started the car with no oil and damaged the motor then realized the mistake and filled it?

[Scorpio6t9]

My car ran great even though one of my pistons was slapping the head, there no way that a car start was started without oil, then filled soon there after, would start knocking only a quarter mile away. The bearings can take quite a bit of abuse before you start noticing knocking.
I noticed when my spun the bearing, at about 5000 rpms, the car hesitated, this was on a tuesday evening (The only reason I noticed it, is because it was the first time my car had ever done anything like that!). The next friday morning I noticed the knocking, I also drive over 100 miles a day, between work and everything else I do.
So from the time I noticed the hesitation, I prolly drove close to 300 miles, not a 1/4 mile. Most likely the damage had already happened before you took it to the shop. It just sounds like dumb luck, i had the same problem with a car over heating. I had just left an oil change place, full service, 30 miles up the road i have no coolant left. My radiator spung a leak, by no fault of the oil change place. Just shear dumb luck.
Sorry to be the one break any bad news to ya, if you continue to go after Pep Boys, good luck to ya!

Got the same problem with mine......the other day i ran my Z to about 6 grand (due to the rain)....then 20 mins later i noticed it was running hot....like 230 ...normally it runs 180-195 .....then a slight ticking.....i thought my water pump had went out.......i took it home with the heat on fullblast.....it seemed to cool down and the ticking get less and less.....i replaced the water pump. tried to fire it up.....wouldn't run.....took off the timing cover and noticed the tensioner wouldn't pump up. finally i got the tensioner to pump up and set the timing. When it finally fired up.....LOWER END KNOCK! what a bitch! The car still runs great (kinda sluggish)but knocks like hell. can i tear down the lower end and replace the bearings? any info would be great

by the way.... car only has 112,000 on it.

cheapest suggestions please....new baby on the way and im almost flat broke!

[darkfox]

you sure its lower end knock? it may be a timing issue. valves smacking in the pistions... you did say you messed with the timing. it is a possibility.

[jamiecavz]

it's quiet when i first start it then it gets worse as i run it. plus it runs great.....doesn't it sound like a rod to you? it sounded like it was comming from the#3 or 4 lower cyl. i had it up in the air when it was running.....and the noise sped up with the rpm's it also sounded hollow.

[Scorpio6t9]

The sound that was coming from my car wasnt the sound of the rod knocking against the crank, it was the sound of the piston hitting the head. At first I thought the sound was coming from the head area also, infact the sound was coming from the head area. But thats not where the problem was.
The engine was completely torn down last weekend, and I can see where the piston was hitting. If is your piston hitting your head, you have a complete tear down ahead of you. there is most likely damage to the crank and the connecting rod.
If you plan on doing it yourself have fun, its a lot more work than you think, if you need any help feel free to ask!!!

[D0M1N8R]

Scorpio6t9 I have a hard time believing that the car had an issue before I brought it to pepboys because it ran great on the way there. I mean never had any engine issues and ran rock solid. The car has 48K miles on it. I mean to me thats pretty new still.
Never noticed any hint of a problem until I drove out of pepboys which first thing I noticed was lack of power. 1/4 mile later it was knocking.
A lab report that analyzed the oil also said that there was no trace of antifreeze at all that would have caused the excessive wear.
