Damn that sux man...

I've been hearing about a lot of lifters failing lately... Both the DOD lifters and the LS7s.. Sux a $5 part can take out an engine...

Hopefully you can just clean it all up, Polish the crank and slap new bearings/oil pump in it.. Time for a cam upgrade since yours is likely chewed up.. Get you a turbo specific grind now..

May as well make lemonade out of this lemon.

Hate reading stuff like this. Glad you caught it though before anything seized or broke. That will help keep the repair bill MUCH less then it could have been.

I wouldn't jump right into rebuild mode. A stuck, destroyed lifter in my brand new 416 is what took my car down and gave me time to think of going this new direction.

Get both heads off and inspect. Pull oil pan for piece of mind. In my case the lifter stuck in the bottom of the bore, cam whacked the axle and roller off of it. Cam was trashed, lifter trashed, metal in the pan. New cam and lifters is all I needed. I just ran an old lifter through the bore by hand over and over until I felt resistance was minimal enough.

Treat it like a junkyard 5.3L before you sink more coin into it. Worst thing happens is you waste some time and head gaskets imo.

It's always disappointing to hear news like this, but I know you will figure it out and move forward. You made short work of the install and it looks like the swap turned out to be everything you wanted minus this issue. Keep moving forward and don't get in a rush.

What were the indications that you were having issues? Did you find the metal when you did an oil change? What does the oil filter look like?

Sucks..at least its winter man..car is bad ***

I've always had a nosiy lifter in the car. I was doing an oil change since it was beat on so much on dyno, found a little bit of metal in the oil. I cut filter open and it has very fine dust.

I also just did a partial comp test even tho motor is cold. 6 and 8 are 148-150 and 4 is 120.

You are going to see if there was a problem with the heads off. 3,5,7 are the ones to pop first on a setup like yours(ask me how know). If #7 is 140-150 I'd proceed to pull the heads.

damn that blows .....

Well pulled a head and found no issues whatsoever... Just going to pull the motor and have it refreshed and install a new cam

Car looks good. What rear spoiler are you running and what are the tire and wheel sizes?

Smoove

Never a dull moment, eh?? I know your pain.

Keep your head up hoss.

StealthFRC

the spoiler is from corvette creations its the s style in carbon.

wheels are

front
17x8 with 255 nitto nto1
best part with this combo is i can turn lock to lock without issues.

rear
18x11.5 with 345 et streets

if you want the offsets let me know and ill find them.

Maybe consider going to tie bar lifters (morel or comp)
I have numerous friends that had same problem with ls7 lifters.
I know it must suck, but you have a nice setup !!

StealthFRC

Yea I still haven't decided what I'm going to go with but it's definitely not the ls7's.

Hope to have the motor out in the next couple of weeks, I'm waiting on a lift I bought to get shipped, once I have that it should make it much easier. I have both heads off, turbod/manifolds etc, basiclly just need to disconnect the abs module and steering linkage and I'll be dropping the front cradle fully and pulling the short block, shouldn't be to bad.

StealthFRC

motor is out, ill be dropping it off next week with the builder. i was able to pull the front cradle in one complete piece and also keep all the power steering lines/pump intact... one less mess to clean up

Smoove

fun fun fun.

Always hate seeing them like this but,..gotta do what you gotta do.

StealthFRC

got that right.
dropped the engine off yesterday, should know by the end of the week where i stand. trying to decide what lifters to get and get a cam spec'd out

Smoove

I hear that.
