Oil Filter; Pressure Issues?!?!?

I have a question for you all out there, but here is the story behind my question.

My hysband works at Repco and had a guy come in a few days back and get an oil filter for his Tez. Same Tez as mine.....RS200 SXE10. So he was given the same filter that I use which is also the one repco shows on the computer for the type of car. He came back today saying that he had changed the filter, turned the car on and then the car stopped. The ECU threw its toys and he puts it down to the oil filter and the build up of to much pressure.

Would this be right?

My husband said there is a filter that is 15mm higher and would probably prevent the pressure from building up way to much.

So here is the question. Which one should I be using?!?!?! I have surge issues with the car sometimes and I wonder if the oil filter could be causing the problem.

the oil filter on the tezza are z386 or you can run a z87 witch is bigger filter i would be trying another z386 and see what happens
as for the ecu sutting the car down for to much pressure havnt herd about it doing that but have herd that they do it if it drops to low

yes, an oil filter can effect your oil pressure. its always best to use a genuine filter, seeing as it was designed for the motor. and they also have a valve inside them, so that if they get blocked they wont stop oil from flowing to the rest of the system. and aside from all else, the filtration quality is far superior then pretty much anything else you can buy.



however, altezza engine ecu's do not measure the engine oil pressure. it doesnt matter what the oil pressure does, it wont effect the engine computers decision making at all.

I would have thought the difference in oil filter sizes if anything would only have made a change in the oil pressure. As far as the car stopping, I know of someone years ago that did not put the sump plug back in, filled the engine with mobil 1 then ran the car for a bit and wondered why the oil light did not go off. Lucky it was a clanky ole 350 and noticed the slick coming out from the other side of the car. There are heaps of dumb arses out the willing to blame someone else for there own stupid mistakes, Can you keep us up to date with this one. BTW, Keith put me onto the larger Celica filters and they work a treat.

Did it actually sieze or just die? Can confirm the oil pressure has no effect on the ECU also, ran mine without a Pressure Sender for a few weeks.

Could it be a possibility that he damaged the Crank Angle Sensor during the filter change? That would cause the Engine to die after starting.

He didnt say it seized or anything, the car just stopped.

The filter I am using is the same as the one the guy was using and apparently Toyota told him that the filter was wrong.

I just wondered if the surges I seem to have trouble with every now and then could possibly be bcoz of the "wrong" filter.

I might try the Celica filter next time and see how I go.

I dont see how the surge and oil filter is related unless its causing problems with VVTi, but that would CEL because the ECU checks to make sure the desired VVTi angle is the same as the current cam angle...

Have you tried cleaning your MAF sensor and doing an ECU reset? It actually works 99% of the time.

Different size filters wouldn't make enough difference to throw a code.

I bet he did something stoopid like leaving the plastic on... or my favorite... filling the entire motor up with oil :)

I'm pretty sure that if the filter element was restricting the oil pressure that much then it would just bypass alltogether.

x2 On doing the Oil Change incorrectly.
