S/C guy needs help

[stang5093]

I just built a 306 with a vortech. Everything runs fine and it has a ton of power, but my problem is that when I get on her my dipstick pops off and oil goes all over. Any of you have had this happen? and ideas other than ditch the dipstick or duct tape it as my chevy friend said . Thanks, Mike

shouldnt it be bolted some where? i had the same probem with mine... thing came undone from head and under WOT it would shoot a **** load of oil out.... made sure i put the dipstick down back in the hole all the way and made sure it was bolted back down with the metal thing at the top to the heads.... i hope this made sence

The part that pops off the dipstick you pull out to check your oil. Damn thing shoots off like a rocket when I lay on her.

try puttin a breather on your valve cover instead of the oil cap.

 

[Euphoric306]

are you still running the pcv system? that will send boost from your intake into your crackcase, and you don't want that

 

[stang5093]

going to have to help me out on what you mean euphoric

 

[luckythirteen13]

isnt the pcv valve a check valve? where air can only flow one way? i have my pcv system with my sc and i dont have oil blowing out of my dipstick or anything like that

 

[Euphoric306]

pcv = positive crankcase ventilation. if you have a line running from your oil filler neck to your tb/egr housing, then your pcv is transferring boost from your intake to your crankcase (where the oil is) and popping the dipstick out like a soda pop bottle cap

there is a small rubber hose that runs from your throttle body to your oil filler location. If that tube is not taken off and capped at the throttle body you will send boost down into your crank case which could cause enough pressure to send you oil dipstick flying.

Post some pics of your setup if you dont know what im talking about and Ill point it out for you.

The hose is gone from the TB to filter. How would I go about sealing it?

if this helps here is a pic of my set up

 

[poneypower89]

Well, if that is truely your set-up.. then the hose im talking about IS already capped like I said it needed to be.. hmmm.. what else can it be... ill think

 

[stang5093]

Its my set up, I just dont know what else it could be. As snoboardcore said should I try a breather on the valve cover? would that work?

 

[stang5093]

Durring normal driving its fine, but when I get on her and she comes into boost i can smell the oil burning on the headers.

If its pressure thats sending your dipstick flying.. then yes, a breather would relieve that and should solve your problem. But it really shouldnt be doing it either way

 

[stang5093]

Yeah I have never heard of that before.

Just out of curiosity... when you capped the hose at the throttle body.. what did you do to the other end where it connects to the oil filler neck? Is that capped to? Because a ran a hose from that location (filler neck) through a smaller filter and then to the air filter. I suppose thats a point of relieving pressure too.. but its so small I couldnt imagine it causing that bad of a problem.

so is that part of your set-up capped too? Cuz I cant tell from the pic.

 

[stang5093]

good question i dont think it is. but like you said its kind of small to make something like this go wrong.

This is correct. You need to run a hose from the valve cover nipple to your powerpipe. Looks like you have a UPR powerpipe. I drilled and tapped mine 3/8' x 3/8. This will allow fresh air to enter your crankcase so your PCV system can do it's job. It will also give another path for excessive crankcase pressure to escape. It's also a good idea to install a 3/8 fuel filter in this line to keep any oil out of your powerpipe. Also, you might try replacing your stock PCV valve with one from a Turbo Coupe, or Toyota Supra.

Here's a pic of my modified UPR powerpipe. I modified the bypass valve fitting as well.
