Warm engine, 1,000 rpm, 50+ psi, 4,000rpm, about 30 psi oil pressure. This seems bass ackwards! Is it a problem? -
Here is a video: The new and old clutch plates do not look the same. Will this be a problem? mkoch

So... My brother has a 98 Legacy, I believe its an EJ25. Bare with me, there is a lot of random symptoms/info here. Occasionally it overheats, so I looked at it. Its spitting out trouble codes P0480 and P0483, which are both fan related. Fans seem to work fine, while watching them. With my scanner, I watched the temp rise (the defrost was on), the fans (and ac compressor) would come on for about 30 sec then turn off. And the temp continued to rise. At 215F I turned off the defrost and the temp returned to 185F. What? Thermostat opened? Extra load eliminated? Weird thing is, when its running hot the coolant doesn't 'seem' to be flowing... Top radiator hose hot, low cold. I can open the radiator cap even when hot, which seems no pressure. I can put my finger in the coolant and its merely cool or lukewarm. Haven't drained to check thermostat, but he says it was replaced 'last time.' Radiator cep he hasn't replaced. So... (In order of my personal unprofessional opinion and economical preference)... Rad cap? Clogged radiator? Failed pump? Thermostat? Head gaskets... I have but didnt use a compression/head tester due to the apparent lack of coolant flow. But theres no bubbles in the coolant reservoir. I dont thinknot will tell me anything. All input appreciated. Thanks all. -
I drove to work. Everything was fine. Then I'm told there's oil under my car. I checked the dip stick and I only have a bit less than full. That said, my car has a drip or few every couple days. It isn't dripping oil in this huge spot anymore. Does anyone think this released from the oil pressure relief valve or do I probably have a bigger problem? I will update the post as I find out more. I have to get my car to level ground at the end of the day and check other fluids. (The second small puddle in the back is AC condensation. Water.)

Hello! I have a 1988 Leone 1800 turbo with air suspension. Something lead to that the compressor was running all the time and broke down (probably faulty damper). I have now changed the compressor (and some faulty rear dampers) and the system fills up and stays filled up like it should. I havent managed to figure out why the compressor doesn't stop when the system (dampers and airtank) are filled up. I tried to change the pressure sensor on the tank but that didn't work. How can I tell if the sensor is broken? I can't get any readings on my multimeter! Anyone with good ideas? I do have the wiring diagram. Tomas

My 1993 California Loyale passed smog for every test except it was 3pts high on the low-speed hc test. I have an SPFI, 5speed, with 180k miles on the car. I noticed the fuel pressure regulator vacuum line has zero vacuum at idle and when I rev the engine! I blew some air into the passage and it only exits from a port ABOVE the throttle plate! According to theory, it's supposed to get manifold vacuum below the throttle plate so it can actuate at idle to reduce fuel. So why is it ported to above the throttle plate at atmospheric? What's funny is I don't have any idling or other problems associated with a faulty fuel regulator, yet it appears it's not doing anything. The shop manual shows the SPFI engine has the port above the throttle plate too. However, it's below the throttle plate for the MPFI engine! Anybody have an explanation for such a strange setup? Is the regulator in the SPFI just a 'fuelish' invention in this case?

Half way through a drive I noticed that I had to depress the brake pedal much farther before braking began (they worked fine when I pulled of of my driveway). The brakes acted as if they needed to be bled. I didnt get around to it and a few days later the left rear wheel cylinder broke and by the time I made it home all of the fluid had leaked out of it. I replaced both rear wheel cylinders and brake shoes and bled the brakes at the master cylinder and all wheels in the correct order. Yet in order to get any braking power, i still have to pump the pedal 6-8 times and even then it sucks. Sometimes it pulls hard to the left, sometimes it doesn't. Needless to say, I won't be driving like this. Could this be a problem with the master cylinder? There are no fluid leaks. ANY advice would be appreciated!! Thanks!

the "Low Brake Fluid" dash indicator light started coming on, i filled it the first time, was fine for a few days, then it came on again, but the fluid in the reservoir was right between "Full" and "Low", and taking on and off the cap of the reservoir temporarily turned off the dash light. when it came on again, i made sure to fill it up completely again. then the next day, i noticed when driving, the brakes were getting softer, requiring very little pressure to push the pedal down about halfway, then eventually all the way down before the car would actually brake enough to come to a stop. i think my first concern was maybe something got into the reservoir when opening and closing it so many times and it clogged the line somewhere, but after talking to a few folks, the thought maybe some air got in and i should just bleed them completely and refill. from what of know, this car sat for probably 7 or 8 years before a got it a little over a month ago. up to this point, the brakes were working, despite the rhythmic shudder which was relative to the speed of the car when braking, like you'd experience on a bicycle if there was a bubble or bum somewhere on one of your tires. this seems more of a fluid pressure issue. the timing belt failed about 2 weeks ago and was not cheap to have fixed and definitely outta my league, as far as doing the work so i'd really like to fix this problem myself because i think i might be within my ability and resources. suggestions? i'm not giving up on it yet, but it's beginning to make me wonder if it's worth keeping for anything other than that fact the body's in good shape. did i mention sometimes it likes to not start? i mean i turn the key, there's a click, and dash lights go on, but that's it, nothing else. sometimes it only take a few tries and it starts up, but sometimes seems like it takes a bunch of tries, then leaving and coming back to it. i haven't had to jump it yet, but i've started carrying around a booster just in case. that's a whole other issue, i'm more concerned with my brakes, considering the safety aspect. very much appreciate, thank you
