Idk what i should do.

Maybe adjust the valves?

does the knock go away after the motor warms up cause that sure as hell doesnt sound like a valve adjustment problem

 

Not a valve adjust!! Rod bearings...

 

Sounds like a typical Y8 -- Spun rod bearing.

 

Spun a rod and getting piston slap. I bet if you check your oil it will be burnt and has metal in it. Time for a new motor.

 

X2...Time for a new engine buddy...

 

Woah!


Sounds more like a valve train issue. Bent,burnt,stuck open valve.
Also sounds like piston slap and a slight spun bearing.

Definaely not a valve lash issue.

Sorry to brake the news again but its time to rebuild/new motor

 

rev the **** out of it, let's see if we can get a piston to blow through the hood

video it as well...

 

lol

 

dont blow it up..

theres alot of people needing Y8 parts for their builds.

find a donor engine and part out the rest.

Or rebuild it.


edit: after seeing the video, I dont know how you can drive around in that car. the interior is filthy!

 

holy knock of molasses that motor is done def a spun bearing or some sort its in the ealy stages of it and will only get worse until it will eventually lock up.

 

Say goodbye to that motor.

 

^ this.

 

or just rebuild the motor or sell it for parts.... your logic is retarded do that with a K-series at one point the D series will become rare because no one gives 2 craps about it now cause they're cheap but they will start dying off

 

^ by the time they start "dying off" nobody will want one anyway. If you have one, leave it alone and daily it, or boost it and when/if it goes drop in something better

 

^ my plan.

 

I may be late but, I wanna prove a point to the OP. Here is my engine, I need a valve adjustment, hard to tell but I do need one. You can hear the injectors firing and I have no knock. Plus, it has well over 300K...unoffically lol.

Lol thanks for all the replys guys.

I know the motor needs replaced. I just made a quick video of it before i pulled it in the garage to pull it.

I found a replacement motor on Craigslist with a 2 month warranty that is going in there. I bought the car knocking, and am just putting in a motor so my gf has a good daily driver.

Im either going to partout the knocking y8 or keep it around and rebuild it with a z6 crank and oil pump.
