that's impossible.. he is the only one.. please dont tell me you went to AED.. haha

no I didnt.

 

[Seer]

So from the thread I have in chit chat. I wonder what caused this, I hope there is not an underlying issue here. I am thinking of moving from TR6's and going to BR7EF's.

^tuners fault tuners fault!!!!!!!!



Lmao. ;-)

 

[lostsoul]

just pop another one in and run it hard and pull again. I got my fingers crossed..

About the only thing that can cause that is something floating around in your cylinder. Usually it's a piece of the piston. That doesn't just happen randomly. You need to get a bore scope in that cylinder ASAP and see what's going on in there.

Hope not that SCJ FRPP short block would be junk then.

Sucks. I don't think Ive ever seen a plug get hit like that and there not be a major issue. Hopefully this is the first time. I know you have been through a lot already with it.

Looked with a borescope. Can't see any damage.

Well then, now I'm lost. Because when I said scope it before, I was sure you were gonna post an update about a cracked piston.

Hmmm

The plug.next to it looked.like detonation. I've read that can be enough to close the gap due to heat. But who knows. The head will come.off.soon.

Looks like it was a good idea of.mine to.start building that 5.8 for my next swap this winter early

When the head comes off, the combustion chamber will tell the tale.

If there was damage would I notice drivability changes?

 

[psfracer]

I would think so.

I suppose what you could do is replace the two spark plugs (I would pull them all to inspect if you haven't already), then do a compression test on all eight cylinders. Hopefully you don't see a significant difference between the two cylinders where the spark plugs were damaged vs the other 6. (+/- 5%)

On my stock motor years ago I had a piece of piston break off--by the valve relief where distance to the first ringland was very thin. Anyway what was interesting about that is the piston looked fine, very minimal pitting, but the combustion chamber on the head was all jacked up.

I swapped plugs from tr6 at .028 to br7ef at .025. Purrs at idle.

Will switch back to tr6 when I switch it back to e85 and the 22 or 24 psi pulley pending no damage.

 

[psfracer]

Well thats good news. Are you going to do a compression check just to see?

Yep tomorrow.

 

[Mystickeith50]

Well if the comp test checks out OK that would be a god damn relief huh.

Those look really good on there. Did you figure out anything on the motor?

I've done everything but lift the head
