Mate, that's no excuse... My car was down for engine problems 8 months... asked questions here not neccessarily referring to parts needed and got NO response. But rather than make a fuss, I called around and went digging till I was lucky enough.

As for parts to buy, people here know the rules and know there are forums dedicated for parts request/ sales and repeat persons can get banned for it. But even that is minor considering you have the arrogance to make noise because people didn't answer you.

Just because you want/ expect an answer doesn't mean it can be answered right away and if you can't have patience to deal with that then you're going to have a hard time here when people can't answer you.

Learn to be patient and expect you have to get info here on your own sometimes...

hi can i install a air flow senor from an 4g63t on my 4g93t

Postby **MISHI** » January 4th, 2011, 6:01 pm

I believe so, but remember it's possible that the airflow may read for more air than the 93T... more air may cause it to run leaner...

fras · Postby **fras** » January 4th, 2011, 7:39 pm

I thought an upgraded AFM would allow your ECU to meter more air and not necessarily cause a lean mixture?

Postby **MISHI** » January 4th, 2011, 7:53 pm

like i said it possible but I'm not sure

iam currently lookin for an oil pump....gettin noise in the valve train goin over 3k rpm...oil pressure is like 45 average underload...which is bad apparently :/ i got a mivec lancer--> GSR fwd.

change engine oil?
check/clean lifters?
check/clean oil pump?

Calibur · Postby **Calibur** » February 8th, 2011, 6:17 pm

engine was rebuilt 9 months ago, mechanics said they serviced the pump before everything went up, i change oil everymonth, my lifters are extremely quiet, jus under load i hear that starving sound, wats ur normal oil pressure @ idle and load?

fras · Postby **fras** » February 8th, 2011, 7:45 pm

I disconnected my oil pressure gauge (fittings were leaking) and reconnected the original oil pressure sensor...

But take down the oil pump and service it, the smallest of particles could cause it to stick!

Postby **MISHI** » February 8th, 2011, 9:11 pm

Why was the engine rebuilt?

If because of some damage or blown engine particles tend to settle anywhere in the oil passages... it's always a good Idea to flush the entire system but even then I've read where filings have settled in oil coolers etc and you just can't get em out. What fras says will definately be a truth... check for any shavings or any particles embedded in the oil pump... if you do then start checking your entire oil flow system for the same.

Kronik · Postby **Kronik** » February 8th, 2011, 10:22 pm

^^when i did my rebuild, i changed my oil cooler due to the whole thing about filings being in the cooler.

my oil pressure at idle is 25psi and about 80psi on load (once it's warmed up)...this is 63T though

fras · Postby **fras** » February 8th, 2011, 11:12 pm

The body/grade of oil would also affect oil pressure?

Calibur · Postby **Calibur** » February 9th, 2011, 8:08 am

the engine was bought and was off timing apparently , and damaged some parts in the block..so it was rebuilt, ive been gettin that sound since i got back my car, they said wen the engine breaks it will go...although i only rebuilt the block and not the head...but i said watever, its still there, and i use shell 10w40 Blue bottle and i tried amsoil 15w40 to see if the sound will go, no luck...i get 20psi on idle and 45-50 on load...so..il have the oil pump check/replaced cause i dont trust it one bit..

u have a 93T GDI or GSR?

fras wrote:The body/grade of oil would also affect oil pressure?

it might, but not by anything significant i would assume......now i know the temperature greatly affects the psi, when i now start the car, the psi is 75 at idle and 95 if i rev a lil thing, as it warms up, the psi drops, when the oil is fully warmed up (80 deg.) it's 25 psi, when the temp reaches around 95 with some hard pulls, psi is like 20ish at idle

but oil pressure is VERY important, cuz when i got my evo, the pump was failing and i didnt know, was getting like 15 at idle and 40 under load......killed my bearings with that, head was good though

fras · Postby **fras** » February 10th, 2011, 8:37 am

Very true Kronik the temp also affects the pressure (noticed this when i had my gauge)... I was thinking about using a "T" fitting so I could connect both oem oil pressure sensor & aftermarket oil pressure gauge!

Kronik · Postby **Kronik** » February 10th, 2011, 8:53 pm

^doesnt have place for a second sensor on the block? my pressure sensor for the gauge has it's own place to screw in

fras · Postby **fras** » February 10th, 2011, 10:09 pm

Using a "T" fitting off the block (where the oil pressure sensor would screw into) would provide you with 2 outlets... u can now use one for oem pressure sensor and the other for oil pressure gauge 8-)

anyone with the cm5a model 4g93t having problems getting coil packs for this engine... im ordering a set from china and i was wondering if anyone else would be interested or maybe a group buy??? costin an average of $400each after shipping and customs... china and japan are the only markets in the world that seem to have this engine and my contact in china says they are 99% comparable to oem and even come with a 6month full replacement guarantee... anyone interested pm me...

ok so now in addition to the icu goin bad on the throttle body the stepup motor is making this loud clicking noise, so i really need to change it. Havent had any luck finding it foreign use so my best bet would be someone who changed their 4g93 engine. any help is greatly appreciated
