my oil light came on after i replaced the headgasket . i know the car has oil in it and idles fine but i drove it down the road for a min and the cel light came on after about a half mile.
what to do?? i am really worried that something might be wrong.

 
Rep Power: 316

Oil pressure light or cel?

 
Rep Power: 301

oil light is on when i started it but the cel came on soon after.

idels fine and stays crunk so i dont think it is the valves bending or anything of that catastrophic nature.

Change oil?---filter?
Does engine rattle?? (make noise)

 
Rep Power: 301

yes i changed the oil and put all new fluids and filter on. the engine runs as if i never touched it. i am afraid to get it up to speed though and see if it acts differently.

 
Rep Power: 316

Must be a blocked oil passage, bad filter (does happen),disconnected sensor,ect! If the motor doesnt rattle, then you "probably" have oil pressure!

 
Rep Power: 454

so does the oil light stay on or just the CEL?

Find out what the code is.

Also did you do just a timing belt, or a head gasket? Your thread says headgasket but you say just timing belt?

 
Rep Power: 301

sorry if there is any confusion. i ment headgasket and i will edit that out. o think it migh t be a sensor but i dont have a obd2 scanner here with me.

do u think it migh tbe ok to drive to town and see if there is a problem (20min drive). after all it seems as if it is fine.

Check v-tec and all wires near the head.

 
Rep Power: 301

well i took it up to 60 for about 2 miles and the engine ran smooooth but i do smell oil. i think this might be some of the oil i spilled on the turbo manifold and exhaust while removeing the head so seeing if it is burning somewhere else is going to be difficult until the rest burns off.

still if anyone has any ideas feel free to comment.

i rechecked and everything seems good but it is possible i am missing something.

i would def get that cel checked out if you havent already. did u tighten up the head to spec? not sure wat else

 
Rep Power: 813

ya have the code checked. did you have the head cleaned and tested before putting it on? im gonna take a shot in the dark and say there is a problem with the vtec oil passage or screen filter. i wouldnt suggest testing this out by taking the engine above 4k rpms tho... check code first and foremost.

I wouldn't recommend driving the car anymore than you already have until you can figure out whats wrong. Doesn't matter if the car has oil in it or not, the oil light is on for a reason.

 
Rep Power: 301

i belive it is the SUB-WIRE HARNESS SENSOR ssince i broke it and had to replace it. still i dont how else to get this checked other than to drive it to town.

P0301 Cylinder 1 Misfire Detected
thats all it is telling me. this happend before i put the gasket in though. i was told it did this because of the cam/turbo set up. i also get code p0300 sometime b/c of other cylenders doing the same.

im lost here. is there anyway to figure this out short of removeing the valve cover?

ok i have a theory and someone tell me if i am wrong to think this.
i removed all the oil and the head too. when i drain the oil i am getting all the oil out of the bottom of the car. well when i removed the head- additional oil came out that would not of come out otherwise. is it at all possible that i might just need to add more oil in the car? i put 4 & 1/4 quarts in like useual but should i of put 5 instead? if i add too much oil i know it can damage the car too.
should i try this?

took it to 4k once on the test drive and it acted fine.

 
Rep Power: 316

NO
I assume you reset the ecu? ie;battery disconect after code

 
Rep Power: 301

i erased it with the scanner.

just tryinh diff ideas

 
Rep Power: 316

The reset make knock out all the lights,ect

 
Rep Power: 301

i did reset it(pulled power cable) and it never went off. never goes back off when i crank it

i think i am going to have to haul this POS to the honda dealership and have them look at it. i realllly dont want to have to do that though!

 
Rep Power: 813

you pulled the cable and the light was still on? cel? or the oil light. cause if the cel is still on, then theres a problem that needs fixing.

 
Rep Power: 272

y did u put 4 1/4 quarts in? that is way over wat the civic should b taking. the most it should take is 3.5 to 3.75. if your dipstick says its at the max of oil then do not add any more oil that would b bad.

 
Rep Power: 301

i have always put 4 qrts in and it has been fine.
i did check the oil stick and it was fine . i didnt add, i was just trying to come up with ideas as to why it might be on.


the cel light is now off. i think it is unrelated to this issue. the oil light is on even when the aux power is on and remains on while crunk. before it would come on for a sec and then flash off once the engine ran for a sec.

****oh i just wanted to say thanks again for any help that all of you have provided.*****

okay this might sound weird, but unplug the gauge cluster connectors and wait a little, then plug them back in. see if this works, then unplug the battery. i remember when i first installed my new cluster, the oil light wouldnt work at all not even when you first turn on the car. then i unplugged the battery and it went back to normal. so you might just have a cluster problem or a faulty signal wire. also i cant remember, but do you have an oil pressure gauge so you can see whether there is really a low oil pressure condition? do you think the oil pump couldve been damaged when you put the head on?

 
Rep Power: 301

well i had a oil pressure gauge but i had to disconect it in order to put the factory oil light back on and to run a oil line to the turbo. just ran out of room for it too. i disconected the battery and reconected it and it stays on. should i leave the cable off longer maybe?
also how do i unplugg the cluster?
where are all the factory oil sensors at?? just to make sure i am not missing one.
i dont think the oil pump got damaged. i dont even think i got near it.

ok the guy at albany honda thinks it might be the oil sending unit and i should check that out.it is hard to tell though because he hasnt seen the car. um where is the oil sending unit?

 
Rep Power: 813

not exactly sure, its prolly in the engine bay somewhere near the oil pan. take off the gauge cluster bezel, there are a couple screws on top and you just pull it towards you hard. then you can reach the plugs on each side or you can remove more screws if you cant reach.

 
Rep Power: 301

ughhhhh frustrating

where is the oil sending unit? both the honda place and my local mechanic seem to think that is what it is. neither one has actually seen my car and are offering ideas but they both seem to agree that is what it might be.

anyone know??

 
Rep Power: 813

i will look tonight in the book when i get home..

 
Rep Power: 301

two new codes! how do i fix this!!!!!
P1106 BARO Circuit Range/Performance
P1259 VTEC System Malfunction

 
Rep Power: 813

vtec system malfunction, check the solenoid on the head. the gasket may need replacing or clogged. but could also be coming up because of the low oil pressure light. not sure on the other code.

 
Rep Power: 301

how do i check the solenoid?

 
Rep Power: 300

Hmm this is interesting, you know VTEC is oil pressure activated right? First thing i would do is check oil pressure. It should be around 10-12 psi at idle and 50 psi at 3k rpm.


You sure you replaced the oil pressure switch and not the knock sensor? They are both in the same area but the knock sensor is held in by 1 10mm bolt. The oil pressure switch has a little rubber boot on the end of the sensor connector.
