lol sludge....it would have to be mud or something.

Unless you pull the valve cover and literally SEE gunk on the cams, its not a gunk problem. A couple things it might be- oil not getting to the pin which locks the vtec cams, weak oil pump, lack of oil


If the cat is clogged the car will still engage the vtec cam because oil pressure does not care about clogged cats. Now if you cant get to 4400 rpm...thats a different problem.

 

If I were you, I would buy a bottle "FUEL SYSTEM CLEANER" and pour that in first. Run in for a while tank and take it from there. Could be a clog cat, but if can also be many other things also.

 

Are you experiancing a sudden loss of power when you hit higher rpms. If this is the case it could be a clogged fuel filter. Im new to the VTEC world so i dont know much about anything engine specific but this happens a lot with clogged fuel filters. Has it ever been changed?

I will change the fuel filter tonight, and I will also buy that fuel system cleaner to see if those work....thanks alot guys

 

I agree with all the advice given. Check all the cheap and easy fixes first. It's unlikely that the dowels are having probs however, I just did a rebuild with a friend and one of the rocker arms with the spring loaded dowel (the last one of the three)was "jammed."

To find your oil screen:
go to the vtec assembly. It's right in front of the distr and has the vtec pressure switch and solenoid. It has three bolts holding it to the head. Be sure to have a oil rag handy. Oil will dribble out as soon as you pull the assembly off.

BTW pulling cams are easy. Putting them back on is a pain. You'll need to move the cruise control, power steering pump, and driver side engine mount to have enough room to tighten the pulley tension bolt. You'll also need two people for the timing belt. One to put tension on the belt and another to tighten the tension pulley.

if the cat is clogged..how the hell do the exhaust fumes get out..it bogs the car out...trust me..ive seen this one more that ONE gsr

 

great, regardless of the engine being bogged down by a blocked cat, oil pressure is related to engine RPM. He didn't say he could not rev the engine did he? No, the problem is that the vtec cams are not engaging fully. = problem in vtec land,not the cat.

 

ok guy whatever you say..you are the king of gsr motors :jerkit:


heres one thread i was talking about..

sorry I'm not really talking about the power loss the poster is talking about anymore. I'm talking about if vtec is engaging properly or not. And a cat is not going to make a difference for those vtec cams to engage.

If we are going to find out what exactly is wrong with that guys car, he needs to post more information about what the car is doing. Reading the description it could be alot of things other than cams or a clogged cat.

 

ok let me be a little more descriptive. When I take off, I have good power up through about 5000 rpm, as soon as I cross the 5000 rpm barrier, I hear the engine making more noise, but the power increase is not proportional. It feels like a natural power curve ( more similiar to a b18a or b), as opposed to a power curve that raises exponentially at 5200 rpm when the vtec kicks in. At times it feels like there is a power surge, but it is spotty across the rpm range, instead of a constant power surge from 5200. Also, Even if I drive the car hard for about 20 minutes, I have almost 0 fuel left.
