had a rebuild done from a shop few years ago about 3 everything possible went wrong when I got the car back oil leaks every were ending up taking it to another very well shop fix all the oil leaks costing me more money about last year, so now I have a leak from a valve not the end of the world getting the head build by LR including the cam , here is the issue pulled the head off have bad rings and there in no hatch marks in the cylinder walls and a lot of carbon build up... the pistons were send to a machine shop and put new rings when HE SAID HE Rebuilt it but guess not , so now im asking u fellow RLers for some help what are my options do I need a new bottom end should I just do a LS1 swap might be cheaper and great power or since my head is getting build by LR should I have them do my bottom end


thanks devon

 

here are some photos

 

Pics aren't working for me.

 

Hash marks on alusil?

 

You beat me to it..

 

What are you basing the "bad rings" on?

 

Blowbye outside of piston head is clean everything else has a lot of carbon build up will try and up load pics again

 

What sort of tuning are you running? What are your AFRs? Sure it's not just the car running too rich?

Do you have a good head to plop on there and do a compression check? I'd definitely do that before tearing into the long block.

 

I'm 14.5 at idle under full boost btween 11.5 to 12.5 and normal driving in the 14s and yes did a compression and cylinder leak turned out a valve is leaking has 12 percent leak on cylinder three and comprssion was low I forgot the number .. that's why Im doing my head but then noticed this issue when it was pulled off

 

JBrown - were you channeling Kimi Raikkonen when you posted this?

 

Idk what channeling is and have no use who this is

 

You won't see any hash marks on our cylinder walls. even new.

 

Pictures aren't working.

 

So what is ideal, just a smooth bore that is round and within diameter spec?

 

Hah Kimi is easier to comprehend than that.
