97 gsr chassis
99 ls shortblock
99 civic si head
boomslang jumper harness
chipped p28 on crome (works in my buddys car too)

brand new oem oil pump
new std size bearings (rod, main, and thrust washers)
black works oil sandwich with -4 line feeding the head
oil galley in head has been tapped and plugged (no i didnt drill to far either)
vtec soleniod is working properly, even installed it on my buddys car and it works on his just fine.

has 70 psi of oil pressure when cold and 60ish when hot

NO cels for solenoid or any of the vtec function


what do i check next??

 

head untouched? been worked on before/ taken apart

 

You should swap the engine into your buddies car next lol jk

 

you think your vtec solenoid is bad, have you checked the vtec gaskets to see if they are clean?

 

Oil pressure switch grounded correctly? Is vtec enabled in the computer? Have plenty of oil? how do you know it's not engaging? It shouldn't feel like it's kicking in, it should just sound a little louder.

 

will you help?? lol

already swapped from my buddys car works fine, and yes the screen was clean as a whistle!

harness is stock with NO check engine lights.
ecu can be swapped to my buddys car and visa versa, still is the same.
i know its not engaging when there is lack of exhaust note change, lack of power in the upper end rpms and i can unplug the vtec solenoid and it runs the same with it unplugged.
i am returning the motor to the person i bought it from and getting the full refund. tired of messing with it!

 

Try to find an oil pressure gauge to make sure the Vtec solenoid is getting enough oil pressure to engage it.

 

Have you tried swapping speed sensors

 

since it's stock harness, is it the ls one you had, or a vtec harness?

 

make sure you have a vtec harness. i dnt think it will work with ls harness

 

It'll work, you just gotta wire the vtec. Sometimes people pin it wrong or the connection is bad.

 

oil pressure at head is 80 psi at 4500.
when i manually give the vtec solenoid 12v (from a wire directly to the battery)
the oil pressure gauge doesnt even move, yet i still have 80 psi!

wont matter, i have that disabled via crome

it is a stock harness, and it is the correct gsr harness
