Got rear ended, then blew my motor. Kill me.

FWIW, id been yanking that timing cover off it definetly doesnt sound like a rod knock it sounds like one of your chain guides broke or screwed right off...i mean for just labour that cover needs to come off to verify...i mean for a couple hours of work...hell i would already be in there if it was mine car...also...the tensioner could be hating you as well
 
secondary chain tensioner is what I'm hearing "through laptop speakers"

I said this way up above and even Dan and someone else thinks that's it.

If I had the loot and that is the noise, I would invest in some new chains, good tensioners and swap them all.
 
There was a pic posted some time ago of a top end timing component component (looked like a sprocket) that they said always breaks when these engines are supercharged because they are made of powdered metal. This one was split in half. Anyone happen to know what I am talking about? Supercharged older Cobras seem to suffer the same problem from what I remember about the thread.
 
Even if it is tensioners the motor has to come out. Cant remove the valve covers without lifting or dropping the engine and then there is no way for ME to realign it all when its back in. So basicly I need a donar motor and then take mine and slowly build it up.
 
As long as you don't go ripped camel on your valve covers, they can come out... Tensioners may seem like a lot of work, and I suppose it may be. But someone that is experienced with mod motors wouldnt have any problem doing them. I'm sure if you can work out for SVO to work on your car, he'd probably be able to diag and repair it blindfolded and one arm behind his back. Don't worry yet man, if it is tensioners your lucky, and the motor does not need to come out... And also... if you have a engine cradle thingy to hold your motor from the top, you may be albe to replace the rod bearings and get a lot more life out of the engine while you are lining something else up...
 
Oh yeah, I took the oil fill cap off and started it as thats the only way I have of seeing if oil is pumping. It is. Its smooth and flowing and no metal chunks. I drained about a quart and didnt see any metal shavings as well.
Taking a long screw driver and setting it on various parts it was loudest against the timing cover. When against the valley it was quieter and towards the rear of the motor it was quiet. But when I put the driver on any of the covers studs or bolts I could hear a sliding slap noise.

Yea buddy that's valvetrain noise. Weather it be a old tensioner, broken guide or whatever. The problem is under the timing cover. I'd be pulling the front of the motor apart right now if I was you.
 
bill you can get the valve covers off with the engine in the car easily. i would get the valve covers off, and take the timing cover off before you go any further with the car, its either behind the timing cover, or its a rocker arm, collapsed lifter, it could be many things, a rod knock, no way not that sound thats valve train noise. sorry to hear this dude, you need to get rid of everything and just ride an old huffy.
 
Anywho I will try and address everything.

Following the tuners advice I disconnected each coil one by one to see if the knocking at least changed tone or got quieter so that I could see if it was a rod bearing. Well there was no change. He said it cant be the secondary tensioner cause the car would not run. I have a close friend that says different so I am torn, I really trust my friend.
More then likely its the front tensioners. So now I have to debate if I want to go through the hassel to check them or just buy a JY motor. The way the engine sits in the Mark it has to come out to change the tensioners cause of valve cover and oil pan interference. So really the cost and time is about the same and then I can keep this motor and slowly build it up over the next year or so.
In any case its down now and I am searching for a sub $1000 beater and the Mark will have to sit for a few months.

Tis what tit tis.



Jamie, could you maybe call or PM me on some pointers on properly positioning the motor to pull the VCs without breaking them?
 
Don't call jamie, call ripped camel :D

Dude... i would consider myself lucky if it were a valve train issue...

its NOT that hard, just time consuming.

And the car will run just fine without the secondary tensioner pumped up, but it can cause your valve timing to be off...
 
i hd that same issue in my first tbird and i didnt have any idea how to fix it check that out first bill and go from there but rebuild her she will b ALOT better man and the best of wish and luck..... damn god will make a way man just be paitent and believe

Not true. All you have to do is tilt the motor (one side at a time, removing the motor mount through bolt) to get the covers off, and there's plenty of room to work in front to get the timing cover off if you need to.

Yup, I have witnessed it first hand. Mike (94M5) swapped timing covers on his car, with the engine in the car. He did it in a couple hours. He didn't have to pull the covers though, just removed the front bolts to pop it out.
 
I Listened to it on my phone the first time, sounded like lifters...but my speakers really suck...I listened to it on my computer at work and it sounds like the timing tentioner on those speakers...I really need to hear it in person, but I don't have engh $ for gas to drive to your house...gonna have to hit up one of my hoes for some cash....lol
 
the first thing i would check is the harmonic balancer bolt, if it is loose it will make a clacking sound. I dont know if you changed it for a different pulley when you went with the blower. Its worth a check though.

Just checked it. Its good.

I just really thuroughly listened to the car and the sound is definatly coming from the drivers side chain. Righ on the cover there its bt far the loudest and muffled everywhere else.

He very recently put on a new crank pulley

I don't know about you Bill, but there isn't a chance in hell I would throw a junkyard engine in under a supercharger. Your best bet is to get some help over there and get your engine fixed, then get a beater. I have a feeling you will be relieved when everything is apart.
 
i removed and replaced both the valve covers on my 98 lsc without touching either motor mount, the pass side came right off after i removed the throttle body, the driverside came right off after i remove the master cylinder from the booster and moved it out of the way, i never lifted or tilted anything about the motor. bill, i have a short block, with rotating assembly in still and heads on it, no oil pain or electronics or intake, the motor ran mint, no noises, no problems, i drove the car back personally 38 miles, the problem the car had was a smoked trans, its the 97 shell that is still in my shop, i wanted to keep the motor whole but too many people wanted too many money makers off of it so i parted it out. its on my engine stand right now, i'd sell it to you dirt cheap, but shipping might blow.
 
Found a 97 mark viii for 1350. Try some car auctions for a cheap DD
