will get a picture up in a minute but can you reuse pistons with det marks?

 

 

As long as the pistons are 100% intact yes, remove all the rings and check the rings lands very carefully for cracks and of course the rest of the piston too.
Shows how much those pistons can take if they are intact as that's quite nasty det marks!

 

You need to switch on the macro function on your camera or back off a little to let the camera focus on the piston crown!!

From what I can see on the top picture, those marks are not det marks. They are impact marks...

 

I was thinking that but as you say it's hard to tell from the pics.

 

 

any better?

 

The sides look like they have picked up from what i can see, this would be more important then the marks on the crown that i can see.

 

As jano said there seems to be score marks on the side of the piston,have you stripped the engine they came out of?

 

only have the pistons/con rods, one piston with marks the other look ok

 

All used pistons will have a degree of skirt wear/markings. If they are not too deep then they'll be fine. The marks on top are impact marks from some debris. They're nothing to worry about unless the ring gap has closed up.

 

Agree!
Measure the ring clearance - not end gap. This will let you know if ring groove width has been
affected.

 

ok thanks will have a look later

 

Hello mate I brought them from jpa on here,

I have got another piston you can have, but the bottom cap for the rod is missing so you would need to use the rod on the worn piston

I'm in Portugal till the 16th but can send it or take to national day mate

Sorry for any inconvenience this has caused

I will sort you out when I'm back mate

 

Thanks

pm'd

 

Replied mate no problems

 

have you had chance to post the piston?
