WTF eveyone Click here I need advice.

[Kenrik]

Ok so many of you know my engine blew up recently.. I was taking it apart so I could drop in a new Longblock and also so I could figure out exactly what went wrong.. When I pulled off the oilfilter (which I had just put on prior to starting the engine after the doing the headgasket) and this is what I see.... it's completely collapsed and it was not full of oil as it should have been... WTF does this mean?

[NIGHTfall_240sx]

only answer i can come up with is...

..sorry bro

[kouki munster]

Don't buy cheap a** oil filters, alaways spring for the good ones.

Sue 'em

That means call your lawyer, You know the one that got you out of jail when they found your meth lab....

[Kenrik]

You think it was the oil filter that ruined the engine? because that's what my brother said

(I felt like kicking him in the balls because he was the one that bought the oil filter)

[Mr1der]

I'd say that's probably why your engine failed...

starving it of oil will do that...

Collapsed in what way? looks fine to me. More pictures? As far as not being full of oil, That is probably due to your oil pump failure. BTW, what brand of filter was it?

[Kenrik]

look inside... you can see the walls of the filter are collapsed in... the brand was "Purolator" my brother got it for me and I was like.. well I'll just use it for 100-200 miles after I put the engine back together then change the oil again... well it only lasted 20minutes..

Interestingly enough my brother said that it was the filters fault the engine threw a rod and that I should sue them to make them buy me a new engine.

What do you guys think?

[SeVa-S13]

Sucks if it did really cause it. I've never had a problem with my Purolators, but I always get the best ones?

There is no way that an oil filter would just flat out do that, although some may be more prone than others. Maybe a mobil 1 or something would have resisted, but that's not the point. The problem was due to something else.

My guess:

If your pump did indeed fail, maybe it somehow created a vaccuum, which did that to the filter. The oil system is supposed to be pressurized, and oil filters can put up with the high pressures, but obviously at less than atomospheric pressure, you would have issues.

Just a guess though.

[Silvia2b]

Did you post this in the nissan online mechanic section? I'd ask nistech what he thinks about the filter. As far as an oil filter causing failure I think that its kinda far fetched to assume that. Now if something blocked an oil chamber internally inside the head or block and oil didn't cirulate through the engine properly and parts didn't get any oil to lubricate and reduce the friction between other engine parts... this seems more likely.

[Red coupe]

how the hell could the oil collaps the filter?pump is before filter and the only way I can even think of for there to be negitive pressure would be a sudden stoppage of flow, but I think that would be pretty mnor, and wouldn;t last long...are there any marks on the side of the oil filter? let see some pics from diff angles, post pics of the bearings and what not as well.

F'ing weird...

[TrunkMonkey]

i've seen 3 things make an oil filter collapse.

1. torquing the filter with a wrench around the center of the filter instead of on the ends.

2. coolant in the engine oil.

3. oil starvation

Hand tightend so not #1

No coolant in the engine oil.. I just did the head gasket and the oil is clean.

#3.... Don't know I'm going to inspect the oil pump.

Not doubting you, just curious how oilstarvation causes it to collaps?

[naed240sx]

There must have been a pressure difference between the two sides of the filter. Caused either by excessive heat created by no lubrication, or something....

Do it anyways, it will make you feel better.

bingo.

id still bet on the pump

think about it, if the filter was causing a blockage, wouldnt it be overflowing?

unless it blocked itself as well as the rest of the line, so the oil never got inside the filter in the first place

Nobody is doubting that it was the pump, except possibly kenrick.

[Red coupe]

well yeah obviously but caused by what? any heat generated would cause it to expand...the pump pushes oil through the filter I think it would take one hell of a vaccume to collaps a metal cylinder as thick as an oil filter, and I cant think of anything that would create that much vacume inside the engine, other then one piston stopping and the piston moving opposite it making a vaccume but......

[PoorManQ45]

I guess Kenrik never got the note. Puralator is one of the BEST designed oil filters available. A LOT of filters are just rebranded purolators. IIRC Mobil 1 may even rebrand the purolators.

maybe this can shed some light.......

[PoorManQ45]

REPOST!

I posted both of those already!

NOte that Mobil 1 filters are one BELOW purolator!

The metal is actually rather thin.(Except at the base where it threads onto the motor)

Take a hacksaw and cut one in half sometime.

[Red coupe]

reguardless It sure you could suck the air out of it with out it collapsing...Naed just pointed out to me...it was the internals that collapsed and not he case its self?

[MS180SX]

maybe there was a defect with the oil filter, which caused the motor to blow? i have never seen an oil filter do that before, and i have probably done close to 1000 oil changes in my career.

[Red coupe]

check the oil pressure release valve that purges exess pressure from the oil pump....maybe it froze shut and the extra pressure collapsed the oil filter and the dmaged internals clogged oil lines and starved your bearings?

[Eikon]

Clearly oil starvation was your problem... whether that is from the filter itself failing or your pump.. I don't know.

My concern though is that it woudn't be worth your time to hire a lawyer... The opposition ask for a history of maintenance... Since you just got done rebuilding it, and you are NOT an A.S.E. certified mechanic, they could very easily pin the issue on something you did wrong.

So, I would file a claim (directly with them, or perhaps through the B.B.B.) But, I would not let it go as far as legal council. You can get a new block for less than a couple hours of a lawyer's time. (nothing again lawyers...)

Perhaps you could threaten them a bit... say that you are consulting a lawyer, but encourage them to simply spring for a new block, and you'll drop the issue.

just an idea..

This would be a good idea, if it weren't a lie. Does anybody think that the oil filter spontaneously crumpled like that? I think that some other oil system failure was the first problem to ocurr, and that any oil filter would have done the same thing, under your exact situation.
