EMERGENCY need advice

[cj]

applied a little grease to the relief plunger bore

Years ago('86), my uncle told me to always do this. I've never once had a issue.

Sorry to see you won't be taking the '02 Blunt.

Sorry again Steve about the trouble. I know your 02 would've been one of the 'stars' of V@V. Keep your chin up! Your 02 rocks and your work on it is inspiring.

If you weren't married I would've sent a couple strippers over to your place by now.

Put the M3 pickup back on the oil pump. There's a relief valve on it specifically intended to prevent severe overpressurization on cold startup. The standard pressure valve on the pump side of the assembly is only intended to regulate hot running pressure, the drain from that valve is too small to cope with cold, thick oil at high pressure.

You'll need to remove the bottom most sheet metal "funnel" from the M3 pickup, you can swap the 2002's screen on instead.

Also use the 11 42 1 278 059 oil filter, it's rated to 30 bar burst pressure.

Hope this makes sense, it's 1AM here and I've been staring at too many '02s and S14s the last few nights.

bent, you have an email address i can have? id like to talk to you

Sure, you should already have it. You've been here, the evening before VintageFest here in Chicago.

BTW, only difference I can find on the Sport Evo pump is that the pressure valve spring is longer, so ostensibly it is set to run a higher pressure. Every other dimension is the same.

And if you want a ride to V@V, get down here by about 4 tomorrow, looks like I might have an open seat. My passenger is threatening to bail on me.

ha hi ben, why yes i do. i guess i was getting you confused with another member named "bentworker". i dont see you on here much.... thanks for the offer on the ride but im flying down with my wife. ill see you down there ben. thanks

she wont mind, really

Just read the whle thread in diagonal.

M10 and S14 engines can have start-up pressure up to 100psi easy. Which is why I wold never install any other filter than a Mann or Mahle. Fram are know to distord and I guess we may want to add Amsoil too.

Blunt read pressures at around 90psi, so I doubt it is a matter with the pressure valve in the oil pump.

is it possible for it to spike and not see it at the gauge though? i cant imagine what else it could be. for the record, the amzoil filter did not blow. the filter that blew was a fram i had laying around. first the cooler blew, then the fram blew after bypassing the cooler. i was running a mahle and always do. if its not the pressure relief i have no clue what it could be

Hi Blunt.

You did a remote oil head installation. Right? Do you still run an oil thermostat? If not, that may be your problem when you blew the oil cooler. Not having a thermostat means the cold oil is highly pressurized directly into the cooler, which might not be built for 100psi. If you still run a thermostat, is it possible it is always open, not working.

So, to recap. You may have blown the oil filter initially because it is a cheap Fram. They do that even with working thermostat. And blew the oil cooler on the second try because the thermostat allows high pressure to the cooler, right from the start.

Does it make sense?

it does make sense but heres the chain of events.

650 miles on the motor with no problems running a mahle filter and 10/40w dino oil

changed oil to 15/50 mobil1 and an amzoil filter-- cooler blew all to hell

i suspected a bad amzoil filter as that was the only new item in the equation . i bypassed the oil cooler altogether and threw on the fram i had laying around. then it blew the fram clear off the car. i know the s14 oil filter head has a thermostat built in. perhaps its not working. my cooler is rated at 175 PSI with sporadic bursts to 325PSI. (taken from earls site)

i only used the fram cause its all i had left. i never use those things but my dad used to and i got them from him. so if i use the new evo pump and m3 pickup with internal 8 bar relief valve (8 bar is 117PSI) im hoping i can alleviate this from happening again. as stated by ben the 02 pickup does not have this horizontal relief valve but rather only the vertical one to regulate hot oil pressure. make sense???

The other way around. First the oil cooler then the Fram filter.

Lee,

When I first saw this thread i went out and pulled apart a s14 filter head and thermostat to see if i could help figure out what was going on. It looks like the way it works there is pressure in the line to the cooler at all times. even when the t-stat is closed there will be pressure from the return side.

hmmm i wondered why it was getting oil to the cooler when the motor was cool.

I suggest a busted thermostat frozen in the open position. If you need a spare oil filter head, I have one I don't use that you could try.
