oil change and oil pressure question


Recommended Posts

hello

i hope someone can give some insight into this.....

 

Bought my car about two months ago

'90 loyale wagon 5sp push button 4wd 262,000 K

 

I just changed my oil

{about an hour ago}

used high mileage oil and filter

added that 'valve medic' stuff

{the TIC was driving me crazy !!}

seemed to work great !!!

prolly only for a little while, but thats better than nothing !

 

only problem i noticed

my oil pressure isn't as high as it was before ?

 

any ideas ?

should i be concerned ?

 

it's still not bad just not as high as it was

was around 3

now around 2 or a bit more

goes up a bit when you rev it real high

but with normal driving

it now seem lower

 

heres to hoping i'm just over reacting !!

If it's ticking quite a bit, then the oil pump seals have failed. They deteriorate and allow air to get sucked in, or something. The result is lifters that won't pump up and bad oil pressure.

 

Search for "oil pump seal" and you should find some results.

 

BTW the guages aren't real accurate.

i'm sure the oil pump seal is going

 

i just don't have the money to do it right now

 

but would the oil filter really cause that much of a difference ?

it's a high milage filter

id'e of thought that would be better

 

on the other hand

its supossed to filter out more junk

 

so maybe its slowing down the whole system ??

Replace the filter. Use only the Subaru one.

 

I'd also use 10W40 oil in that engine. Get Quaker State at Canadian Tire. Use 20W50 in the summer.

 

On my Subarus, (I've had 4 that all went over 400,000 km), lifter ticking occurred only when it was time for an oil change. I always changed the filter at the same time. None of them ever needed work on the oil pump.

my 86 spfi a/t fwd sedan started ticking really bad , and yes subaru did make a spfi in 1986 but only fwd and in a sedan , anyways i decided to change the oil to chevron 15w40 , within 100 miles the ticking was gone , and good oil pressure just like before the ticking :cool:
