Hey I need help with a problem. as you guys know i bent a few valves in my H22a4 awhile back and we pulled the head to get everything fixed. well i get a call from the guy at the shop and he tells me that he thinks this head has been pulled before. i hightly doubt it since its low mileage and there was no sign of it before. the motor is a 2000. but he says its missing the oil control jet.. he said he called honda and they said its suppose to have it. BUT well he went ahead and put the head back on.

Could someone help me out here and correct me, but shouldnt the h22a4 have one. my vtec worked perfectly before.

while the head was off and the car was at the shop, could someone have swiped it from the motor? ive had a few problems with **** like that before. and what kind of problems could there be without it?

Please help me out guys.

Thanks In Advance

 

Problem would be starving the bottom end of oil. All oil will flow unrestricted to the cylinder head and will also have lower oil pressure.

However, the prelude has 2 oil control jets. Neither of which is between head and block like a civic, but rather there is one located under the #1 intake cam main cap and the other one is located under the #1 exhaust cam main cap. Pay particular attention to which orifice came out of which side as they are both different and will only fit in their corresponding side.

Hope this helps...

Could you take a picture of that oil jet.. I'm having a problem with an H22 and no vtec. The head was pnp so I'm wondering if they yanked some ****?

Thanks.

-- ok nevermind I know what those oil orrifce are. So if I have those, and I have a working vtec solenoid and also I know that I have a signal that goes to the vtec solenoid.. what else would be wrong for vtec not to work?

Also, the main oil control jet is under the #3 cam journal. Most machine shops don't even know that it resides there, so typically, it is never removed.

As for VTEC not working, could have a blocked passage. I'd remove the VTEC solenoid and see of there is anything restricting flow through the filter screen. Have seen this before after machining was performed.

Let me know what you find...

 

Weird enough all the plugs or control oil orrifice were there.. may we missed something that was in the block, I'm not sure :-\ So I fixed it quickly by creating a custom /seperat oil line. Kinda like the LS-VTEC run. I had an oil pressure gauge that was telling me that not enough oil was getting pumped through the head. So I just dumped a bunch more, and now VTEC kicks Hard.... I love it Maybe one day when I got lots of time.. I'll take the head out and look for every orrifice/plug that is suppose to be ther. Especially now that I have a blown up view of the head+block assembly, I think it will help. Thanks for the advice though
