Bubonik Posted November 18, 2004 Share Posted November 18, 2004 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 !!

Mudboat Posted November 18, 2004 Share Posted November 18, 2004 I suspect the filter. You might want to get another one... Quote Link to comment Share on other sites More sharing options...
Nug Posted November 18, 2004 Share Posted November 18, 2004 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.

Bubonik Posted November 18, 2004 Author Share Posted November 18, 2004 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 ??

canajun2eh Posted November 18, 2004 Share Posted November 18, 2004 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. Quote Link to comment Share on other sites More sharing options...
86subaru Posted November 18, 2004 Share Posted November 18, 2004 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: Quote Link to comment Share on other sites More sharing options...
