Pistons?

[smiddy]

After reading another thread on here I took out my plugs to see if there were any markings on my pistons. There is a small circle but no numbers or letters. Are these standard as my block was re-bored and I'm wondering if Nissan did an oversize set.

if the dont say 54c then they are aftermarket

how would you see the 54C?.......after you take a plug out and shine a torch into the bore? all i can see is a circle on top of the piston about the size of a penny...with,no,markings?

please advise.

thanks,

Lee

you cant miss the 54c stamp,if you can see the circle on the center of the piston you would be able to see the 54c next to it on standard pistons.

 

[PulsarLee]

should,the 54C be inside the circle?

Cheers

 

[red reading]

no just to one side,as i said you won't miss it if its there!

I have not had the pleasure of removing the head (touch wood) so I can't really advise.
The best I could do is email you a couple of rear engine pics which might help you locate and navigate to to offending critters!

Weird, just replaced my plugs - all my pistons say V44, any idea what these are?

Coulnt wait to get rid of the tickover control gubbins down the back of the engine. Makes removing the head (almost...) a pleasure.

Two extra turns on the throttle stop. Mind, mine is a rally car

Lol, Thanks Dave, I'm available for weddings and birthdays. The engine has not ran for 7 years. Don't know anything about the engine or previous set up. I've plumbed it all back up to run standard setup, so i'll give it some right foot to give bores a clear out and have another look i reckon,

They look after market as you can't see the 54C stamp on them!

Look stock to me as you can see the circle in the centre of the piston, the 54c is to one side of it

If that's the case, I'll shut up then! :hide:
