Rebuilt Engine, glazed cylinders?

[burn_your_money]

So I bought a 1.6 TD engine today (Don't worry, it's not for me ) and the guy had it re-ringed with all new bearings, head and such either 1000, 200 or less then 100 kms ago.

Initially he told me that it was about 1000 kms ago, but then once he saw the compression numbers he said maybe 200kms, then he changed it again to less then 100 when I tried to low ball him.

Anyways, the compression numbers are 420-360-350-410. Seems a little low for new rings no?

After he settled on his story being that he ran it less then 100 kms he added that he did start it about 15 times to "let it warm up." I'm assuming that he just let it sit there and idle away.

So I'm thinking that the cylinders are glazed but I'd like some opinions please

Remedies for the situation would also be appreciated

Seems interesting that the two weakest cyls are side by side..  Could just be coincidence..  Did you do a wet comp test, or put air to the cylinders to verify a ring issue..  I woudl think if it were a break in issue they all would be about the same compression even if it was a low number...  Maybe it was a poor honeing job..   YOu have the "run it and see" option available, but with the changing story I would be worried about what ACTUALLY was done, and how well..   

On a side note, after about 8,000 kms on the reringed engine in my oled caddy the compression was something to the tune of 350-250-250-250....  I had the bores measured before the job and they all came in with about .05 mm wear..  (I home I'm converting to metric properly)..   During the autopsy the cylinder walls appeared to be normal, bores were still at about .05mm..   Tried a different brand of rings, and it was golden.. Compression was about 485 acriss the board...
For the record I replaced the Top Line Rings with Grant rings..

also - consider which cylinders are low. Maybe you are dealing with a headgasket issue, warped head etc?

A leakdown test would be valuable if this doesn't resolve itself. Is the coolant stable (as in not blowing off)?

Was the guy from Haliburton ON ? ;-)  Sounds like he was full of it. Maybe he just cleaned up the outside and called it rebuilt?

i had an engine with glazed cylinders once, put dino oil in it and ran the piss out of it. pretty soon compression numbers evened out and it quit burning huge quantities of oil. i figured i couldnt really hurt much giving it an italian tune up, since the bores were already toast and i was gonna prolly have to pull the head anyway, but it worked fine, but just because it worked for me, it may not work for that engine. did he start it on synthetic oil? if you run synthetic in a new engine, it takes for freakin ever to seat the rings.

The engine is out of the car. It's been under a tarp in the backyard for about a year.

When I pick it up and bring it to the shop I'll do a leak down test on it.

I don't really want to go through the hassle of installing it in a car and the seeing what happens, although I also don't want to hone it haha.

If I do pull the head, do glazed cylinders look just like the name implies?

honestly ive never actually seen a text book case of glazing first hand. i just assumed i had some glazing, but it might have just been the rings were not seated. but it started like crap, smoked, and burned oil. then came the 2-300 mile italian tune up. after that cold starting improved, it quit smoking, and oil consumption went back down to where it was supposed to be.

Well I'll take some pictures if I do end up going that route...

Thanks for all the insight everyone
