There was no play, of course, but I was wondering if such scoring is excessive for these engines. Unless you've looked at the bearings of a similarly aged rod, you never can tell, canya?
They're Vauxhalls after all, not expected to live forever
I had also reconed the turbo at the time, (and again, and again and again and again)
The reason most of this carbon crap is on the pistons is because of the previous crappy recons - the pistons looked fine first time I opened them.
As for the rings, well what do you expect after 95K miles?
First time round I ran out of spare time, and Russ had said that his was doing fine with 160K miles on the clock and 20psi, so I thought "it'll be fine".
It was not fine lmao
Originally posted by 0ddball those pistons look very familiar. took mine out last night, the oil scrapers were flush with the piston wall. all gummed up and shagged. whereas the comp rings sprung out like new.
The dangerous bit is the carbon deposits UNDER the compression springs.
They are meant to have a certain degree of freedom, up and down, right-left
Once carbon builds up they get stuck and off you're to the boring machine...
Well, the bearings are ***ked. Get them changed. Look at the crank too. Shouldn't be scored like that.
I could see wear on mine ( 90k+ ) but not scoring like that.
I went for a crank regrind and a new set of shells, as the cost is minimal overall.
I'm not seeing a very good cross-hatch from your glaze braking, but maybe it's just the photo. I'm also very suprised if you've done that with the crank in place. Freshening up the bores is a take the engine out and get the crank off exercise really. I hope you manage to clean it up extremely well.
