Hello, I'm new here. I have a 200sx, ca18det engine. My car's dipstick keeps on poping out leaking motor oil and if its not that the valve cover pops out. its like theres alot of pressure. I did block one hose, the breather hose going from the valve cover that was connected to the air filter piping. I don't know if thats causing the problem? The car does not respond. Its an automatic. check turbo, its okay. piston compression is 12 11 11 8.5. if i step on the gas its still slow theres no response. I'm sorry for the english.

But anyways, Yes there is too much pressure built up in your crankcase by blocking that blow by hose on valve cover.

either connect the blow by hose or install an oil catch can with breather (see below) to that blow by on your valve cover to release pressure out of your crank case.

Thank you very much. If i connect back that hose it makes more smoke. At my exhaust. Can i use an rb20 engine sensor for my TPS. Throttle positioning sensor? Or should i get the whole body and put it in mine? Is that possible? I can't find that sensor anywhere in my country.

I mean coming out of my exhaust*

If it smokes through exhaust then definitely oil catch can is needed.
However it shouldn't spit out oil that much to begin with. Try to replace PCV valve.

Not sure why you are trying to replace TPS sensor?? Where in SE Asia are you?

Brunei daruassalam a small country. No we are not terrorist hahaha. The car just don't respond when i step on the gas they say its that. Pcv valve is very hard to find here. Is there a replacement?

azmi604

So yes i use the hose again but there is still
Alot of pressure. No smoke coming out from the exhaust but i can see the oil is getting out from the holes of the pcv valve. Plus the car is kinda heavy now. When i go up a hill its like I'm towing something.

Well the part # is 11810-E3001. If there is a Nissan dealer ship or auto parts store near you, you could try to ask with that part #.

The blue blocker was the one that i block. Now i use it back the car feels so heavy.

You do have one piston that's at 2/3rds of the best one. That compression discrepancy could cause that much blow-by, and bad performance, I think?

azmi604

Yeah but ill just try to get the catch tank. Even with the one piston. It shouldn't be going that slow right? When i plug in the breather hose. I'm sorry i just got the car 4 days ago i don't know what the dude been doing with it for so long.

Is it okay if i go for the cusco oil catch tank but its without a breeder. Theres works with a breeder but its black colored. At least cusco is crome hahaha plus they give me the hose.
