Oil filter blowing seals?

Hi, I wonder if any of you guys can help. A friend of mine recently purchased a 2005 Jimny and after a week of ownership the engine holed a piston. The garage she purchased the car from had the engine reconditioned and returned the car. At the weekend she came over as it kept stalling, I put my code reader on it and found it had a faulty 02 sensor and someone had removed the check engine light bulb from the dash panel.

On sunday she went to go out, started the engine and it dumped its engine oil on the floor. On inspection her husband found the oil filter had blown the seal out. Today she had a local mechanic come out and fit an 02 sensor, CEL bulb and new oil filter. It started fine and all seemed good, no check engine light and idling great until......

As soon as the throttle was applied it blew the oil seal/gasket out of the side of the new oil filter he removed the filter and refitted with the seal relocated and started it back up, you can see the oil filter seal expand if you increase the revs very slowly. The mechanic has advised the car is towed back to the garage that reconditioned the engine as it may have a blocked oil way or faulty pressure relief valve.

Anyone heard of this happening before or could shed anymore light on the problem?

Sorry for the long story but thought it best to tell all lol.

It could be that the head gasket is wrong. if its the g13bb there are a number of versions, at least one has different oil ways

Is it a genuine filter that has been fitted?

I never fit pattern parts when we are talking filters

No, one was a Mann and the other a Coopers, both OEM approved spec though.

I thought the same but it doesn't explain why it was fine for about a week.

Take it back for investigation.
If the wrong gasket is fitted the cam will seize from lack of oil.

TBH I would have thought that the oil pressure relief valve is the culprit, it should open and reduce the oil pressure even if an oilway is blocked.

Let the people who did the engine rebuild sort it. There must surely be a guarantee.
