yeah true, the last owner has changed the main oil seal about 8 years ago from Toyota (lol, not sure why not A*W). Also, the mileage is 192K so probably the seals have gone bad. I was just wondering about a good garage because I'm tired of makabases. I guess the best options would be to take the car to Toyota's pitstop or AWM then

Well, the oil level reduces a lot, however there are no identifieable oil spots under the car when it's parked and it seems like it loses oil when the engine is running. Coolent level is not affected and there aren't any white smoke or smells while the engine is running. Recently the car was lifted to do a suspension repair at auto miraj and they pointed out that there's a oil drop and a possible oxidation on the gearbox and engine joining bolts and said it's probably leaking oil from the main seal. ps: the tappet cover packing was replace by A*W last year too but there aren't any visible oil streaks around that area.

Guys, any suggestions about a good place to do an engine oil leak repair on a nissan around kottaw/pannipitiya? I tried to go to palitha but he's way to busy

hmm, are you sure the power loss is due to the gear box? I'm also having same symptoms but mine is a Nissan sylphy. Please update this thread if you find a good garage to diagnose this ☹️

hey, what's this ignition coil failure you mentioned?

no mchan it never happens on startup, idle or while revving in neutral/parking. Only happens while moving around 1500-1800 rpm

In my case sounds more like a loose spinning chain noise. I thought it might be the timing chain but it doesn't happen in idle or when revving in neutral

Did changing the pulleys fix it? I also have this in my G11 and goes away when increase the rpm a little bit. Usually comes around 1500-1800 rpm

I'm in colombo mate. Fuel filter was also replaced when I replaced the pump motor

Check CVT fluid condition – If it's dark or burnt-smelling, consider changing it (but be cautious with CVT fluid changes if it's never been done before). If it's not a CVT, check for clutch slippage in an automatic or manual gearbox. 5. Exhaust Backpressure Issue? You mentioned: "feels like the engine is trying to push away air." If the catalytic converter is partially clogged, it could cause power loss and hesitation. Try removing the upstream O2 sensor (temporarily) and see if power improves. Check for unusual exhaust smells, rattling, or excessive heat from the catalytic converter. Next Steps: Spray test for vacuum leaks (carb cleaner near intake components). Clean throttle body & MAF sensor. Check fuel pressure at high RPMs. Check transmission behavior (if CVT, test for slip). Test for a possible clogged catalytic converter. -ChatGPT I did test for vacuum leaks and there were none. The idle is rock solid at 700 rpm. MAF sensor was also cleaned during the tuneup I checked the gear oil and It looks red too. Do you know a place where they check the fuel pressure?

Guys, I recently bought a Nissan Sylphy G11 2005 as my first car. It was fine when I did a test drive, but after I bought it, I took it to a service station (my bad for not going to the dealer) and did a regular service. When they emptied the engine oil there wasn't much oil and it was dark coloured. The previous owner said he used 20w50 oil so I used the same during the service. However, after I returned from the service, there was a significant hesitation in the engine, which even stopped on a small hill. Once I started again and revved a little it was kind of okay. At this point, the check engine light was lit and the code was P0171 lean condition. So after this, I took it to A*W and they suggested doing a tuneup. I did it from A*W and they replaced the spark plugs and also discovered there was a heavy sludge formation. They removed the valve cover and cleaned most of it by hand and suggested changing oil in shorter intervals. They also recommended to change the injectors as they were kind of damaged. So once I returned from A*W the pulling power was good on the engine but right on the next day the CEL came on again and the performance was kind of bad again. It was again a lean condition. After this, I did the below, - replaced injectors with refurbished ones (didn't fix anything) - replaced the oxygen sensor (was really good right after it was changed but went back to the same problem in a couple of hours of driving, live data scanned shows proper values ) - started to use 95 octane petrol (slight improvement in the performance and responsiveness, somehow the P0171 code is now gone the CEL is not lit and there are no other error codes) - replaced the fuel pump motor (had a significant improvement in cold starts and pulling power) - replaced air intake manifold gasket (no improvements) But still, the hesitation is there. it's most noticeable when I fully press the accelerator, it starts with a wired low rumbling sound and the sound goes away after it picks up rpms. And sometimes the engine revs around 3000 rpm but doesn't pull the car enough relative to the rpm. I have also noted during this time the rpms increase incrementally like a little bit and a little bit and not smoothly and feels like the engine is trying to push away air. However, on high gears, the performance is really good and I can cruise around 100 easily. Recently I did a break service at automiraj and when they lifted the car we saw there was a small hole in the resonator in the exhaust line. Not sure if this is the cause for that. Has anyone had any similar experiences? I'm really fed up with going to makabasses because no could identify the root cause. I would appreciate if anyone could give any ideas about probable causes.
