87TPI/SS

so today along with finding another problem I removed my oil filler cap while tryn to find another problem/noise (while running) and when I did it made a loud and hard sucking noise through the oil fill hole in the valve cover the car ran up a few hundred RPM's and seems to have way more acceleration/ response and over all power........any suggestions!!!

Also while the car is running if I put my hand over the oil filler hole it sucks my hand with a great deal of.......SUCTION!!!

The car runs great just got of the road for a 150 mile trip with no problems and this motor has been in the car 7 years problem free.

thanks for any ideas or help

Its called pcv system.

87TPI/SS

I understand that but my pcv system is working as it should be and I believe the vaccum lines are all correct but it will suck a bruise on the palm of your hand if you leave it a long time.......

87TPI/SS

is this common or does someone think I have a problem?

Thats a new test , how many inches a hg does it usually take to bruise your palm.

87TPI/SS

about 2-3 minutes!!!!

bump before I tear this thing apart!.......

That sounds excesive, there shouldn't be alot of suction inside the engine block, just a little. Probably going to have to take it apart. Start by performing a compression/leak-down test on each cylinder. Maybe pop off each valve cover and rotate the engine by hand while watching all the rockers to ensure proper movement/action.

Hope this helps.

bad intake gasket into the valley?

87TPI/SS

anything else to support this idea because it runs great and I mean great chirps 2 and 3 no problems just done 150 mile in it round trip no problems at all......

BTW thanks for you guy input!

87TPI/SS

and I was thinking the PCV sucks my finger when you put your finger over it so..... with the engine sucking like it does and the PCV sucking is that a fighting against each other type situation

if you pull the pcv valve out does the suction at the oil filler less? does the the pcv rattle if you shake it. It should have that much vaccum on the engine.

87TPI/SS

no change in the suction of the engine

no rattle in the PCV

rusty vango

i find it depends upon the website you select!!!!

Well there is a problem

there shouldn't be any noticeable vacuum in the crankcase.
you may have 2-3 problems.
with the oil cap on, start the motor and pull the PCV valve and with your finger, cover the hole in the valve cover. does it develope crankcase vacuum?
if it does, then the lower intake gasket is probably leaking and you have a problem with the crankcase vent.
if it doesn't, then you have a problem with the crankcase vent.
with the valve not rattling, go a head and replace it.

Ok here is a small video of what im faced with thanks

Ok!! so is there something wrong or is that ok or do you even know you've made various stupid comments but never had anything to say worth a damn if you dont know or don't have an intelligent response please stop getting on this thread I really need some info because Im new to this whole TPI set-up thing and wanna take it on the road real soon but I dont know if its something I need to address....... thanks to anyone else who has helped!

Have you put a new PCV valve in yet? If it doesn't rattle, you need to change it. They are available from most auto parts stores for less than $10.

Pull the PCV and plug the hole with your thumb, does vacuum still build without the PCV valve in the valve cover?

Hope this helps...

87TPI/SS

Yes I replaced the PCV and the hose just because iI am looking a getting a vented oil fill capand yes if i put my finger over Pcv hole it dose cause a vacuum...

87TPI/SS

Also a higer RPM ranges it starts to push oil out the dipstick base where it meets the block and I have replaced the tube and tried to prevent the leak so i think it has something to do with this problem

Seriously? you haven't put a vacuum gauge on, if your going to put a breather cap on plug the hose on the drives side to the throttlebody. are you having some running issues or something. all the information is posted above.

You might place your vented breather on the passenger side not so close to your pcv.

skibum2100

There isn't supposed to be oil coming out the dipstick tube and there isn't supposed to be excessive vacuum in the crankcase. As mentioned above: the lower intake manifold-to-head gasket is probably leaking, but how do we test that...it is probably leaking on the crankcase side rather than the atmosphere side. Spray some carb-cleaner around where the intake meets the head, if the idle increases you found your leak.

Can a leaking valve seal cause this much vacuum...? A combination of stuck valves and leaky piston rings may cause this...

Perform a compression/leak-down test on each cylinder.

Hope this helps.

i recommend against using a crankcase breather cap. they don't filter the air very good and it will leave oil residue on the valve cover and you'll probably smell oil inside the car.
add to that, if you have emissions testing where your at, it won't pass.

no doubt you have problems with the crankcase vent. its in the other valve cover and runs up to the throttle body.
there are 2 vent fittings on the right side of the throttle body. the top one is for the crankcase vent. the bottom one is for the canister purge system.
the fitting for the crankcase vent is larger than the one for canister purge.
if the hoses are swapped, then you'll have intake vacuum going to the crankcase vent.
you wouldn't happen to have a PCV valve in the right valve cover?
if you do, then the crankcase vent will not work right.
if you don't have a working crankcase vent, the motor will build pressure in the crankcase and you will have oil leaks.

to check for the intake gaskets leaking into the crankcase, pull both the PCV valve and crankcase vent from the valve covers and seal off both holes. pull the dip stick and plug a vacuum hose on the dip stick tube and put a vacuum gage on the other end of the hose.
at idle the vacuum gage should show little to no vacuum.
if the gage climbs much over about 1 inch of vacuum, then expect the intake gaskets to be bad. if it goes to near intake vacuum, then something is wrong, most likely the intake gaskets.
running too much crankcase vacuum will kill the main seals.

valve problems won't cause this, neither will bad rings.
bad rings will cause excessive crankcase pressure known as blowby.

OMG!!!

THANKS TO EVERYONE FOR ANY ADVICE GIVEN EXTRA THANKS TO DENN SHAH FOR THE ADVICE THAT FIXED THE PROBLEM I HAVE THE CRANKCASE VENT GOING TO THE PASS SIDE VALVE COVER CREATING THE VACUUM IN THE MOTOR

New question what do i do with the ports in the TB since i dont need them in my swap?
