oil leak

Hey just need some help i noticed today there was some oil on top of the head where the spark plug wires go in i have seen it there before but today i installed a boost controller it was at 9 psi before but i put it up to 12 psi and there is a little more i cleaned it and went and drove it then checked it again and there was some on it looks like it might be coming from one of the screws on top of the head how can i fix it or whats causeing the leak.

Well i was cleaning the valve cover a noticed it was cracked around one of the screws that are by the spark plug wires this cant be good what can i do with this prob. someone help.

If the valve cover is cracked then you'll need to replace it with another one. When you put the replacement one on you'll have to be careful about tightening it down. If I remember correctly, you need to tighten them by staggering from one side to the other until they all have been tightened equally so you don't crack the next one. Don't overtighten either or they will crack. Just get em a hair past snug.

is there a way to seal the crack till i can replace it.

epoxy may work.there is no pressure so any good sealant may hold

just another quick ? how much boost can i put to the engine without blowing it up.

Well that depends on many things...
1. The integrity of the motor itself.
2. The size of your injectors and pump.
3. Your tuning capabilities.

It will vary for each motor and setup depending on all these combinations plus several other mods.

ok well stock internals i have 550cc injecters with a 190lph fuel pump and in my signature block is the rest of my mods also i just got in my apexi safc 2 im hooking it up soon what kind of senser does it have is it the karman or somthing else.

Yes, our cars use the Karman Vortex style of MAF's. Do you have a datalogger for doing this or are you going to be using the o2 voltage reading? I didn't see anything in your sig about that or a wideband. That is why I am wondering... You will need one or the other to properly tune it.

i dont have a data logger but i have a narrow band meter how hard will it be for me to tune with just using the narrow band i know i need to to get a wideband but just dont have the money right now.

Well, you can do the AFC blue wire mod, which will give you your o2 voltage on the AFC and you'll be able to halfway tune it like that. Certainly not the best way, but it'll work to an extent. I would definitely consider a wideband as one of your next few purchases before anything else...

When u say the blue wire mod what do u mean how do i do that.

Search for it. All over the internet. Includes diagrams too.

i found it but alot of people say not to do it why not?

Because its not the most accurate way to be doing it and when you do inaccurate tuning then you risk blowing something... In my opinion, a wideband or datelogger is much cheaper than rebuilding a motor. :wink:
