So i've let a professional company over here ultrasonic clean my injectors, unfortunately they couldn't test it afterwards cause they hadn't the tools for this specific side feed injector. :( I mounted them yesterday and the car seems to rev just a bit better. Yesterday i've also changed my oil and ...

I want to add that i installed a fuel pressure gauge (not regulator) and sometimes the fuel pressure drops to 0 within 1-2 hours, sometimes the fuel pressure is still pretty high after a few hours. How long should it normally take for the fuel pressure to drop to zero? I replaced the pressure regula...

I don't have a wideband or a probe :-( I do notice though when i just started the car of drive a short distance i can smell the exhaust gasses, then it smells rich. But yesterday i toke the dipstick out and the oil cap and smelled the oil. And it really smells like fuel and/or exhaust gasses. The ex...

today i discovered the oil is smelling really like gas! Maybe it is overfueling? How to check for overfueling?

The car sometimes hestitates, but most when it's cold. When i look at the tailpipe it's black (on the lower side), more like on this pictures: http://i40.tinypic.com/jpzwcz.jpg https://lh6.googleusercontent.com/-loXA4Ju0MVc/UXcEAoV1HZI/AAAAAAAAC_o/LDOI1lTyGVg/s896/13+-+1 When i wash the car, i also ...

The rings that are used are OEM Toyota ring std size. I've only used OEM parts for the oil pump, all bearings, gasket kit, pistons, rings, etc. Only the water pump is a non Toyota brand. The plugs look all the same without excessive oil or whatever on it. I have a picture somewhere but cannot find i...

Sorry i didn't explained myself too well i think. The PCV is going to the vacuum rail yes. I've also replaced the PCV valve for a new one, but that didn't solve it. What i meant is that on the right side of the cam cover, there goes a (breather) tube to the intake air hose. Like on this picture: htt...

Today i checked the intake and there was a splash of oil in my intake. Is that normal or is it caused by too much crankcase pressure?

The pcv valve is new, what are other cause of the crankcase pressure being high? Can the head also cause pressure?

Redline it every day with plenty of engine braking from high rpm. Probably won't fix anything, but you will have some fun Haha that's true :D I do doubt though that it's coming from the rings. I think so while compression numbers are exactly the same as after the rebuild, not the slightest change a...

But when the rings would've not seated well and be worn, i'd most likely would have lower compression readings wouldn't i?
All the cylinders read about 190 psi which is pretty well i think.

What i've also noticed by the wat, that when i drive constantly for about 100 km or so the cloud is absolutely bigger. So the longer i cruise and then accelerate the more smoke i produce. Normally it isn't a big cloud, more like a puff. But after long driving its a pretty big puff. Maybe that are cl...

Yes they measured the bores and it was just perfect. There was almost no wear on the cylinder walls, the rebuild shop told me they even thought the engine might had even less then the 90.000 km that was advertised. They did make new hone marks, mounted new oem piston rings and all oem bearing. No ov...

Hi, I'm new here and hoping you can help me out. I have a1994 corolla with a 20v engine in it, the blacktop. The engine was rebuild about 10000-12000 miles ago. It recieved new rings, crankshaft and rod bearings. The head was partly rebuild. The garage grinded the valves and replaced the valve stem ...
