Oil Dipstick

[FULLPWR]

Something I have been dealing with but just forget to ask.

when I chk the oil and install the dipstick all the way it engages fine at the handle and end of the tube like any other dipstick does.

but...... when i go to check the oil few days later its allways sticking out about a half inch or so, like I didnt engage it all the way.

so i've pushed it back in took for a granny few mile drive and ck it and its fine. but when i go terrorize the neigborhood and chk it it is out...

I dont know if I need another stick or tube or what.

any ideas what causes that?
and any ideas on the fix?

:cheers:

Crankcase pressure may be building up pushing the dipstick out.
Time to give the PCV system a good look over.

Agreed, something is not right. Check PCV out sooner then later :)

I wouldn't be wailing on it until you get it figured out. Too much crankcase pressure is not good.

a month ago or so, i just replaced them, maybe 300 miles on them.

but will check again too make sure.

ok chk'd the pcv's they are fine..
messed with the dipstick and it really doesnt seem to be enaging, like a snap fit or tight at all.
I barely pulled on it and it moved out.

I have one that the t handle is broke off, but seals great it you want to give it a try

[FULLPWR]

yea !!! maybe so, where it says " at the bottom of the tube " forgive my ignorance

but does that mean i have to completely remove the whole tube from the side of the motor?

thanks

That is the rubber seal for the bottom of the dipstick tube. The dipstick tube should not move since it is bolted by a flange to the exhaust manifold. There is a rubber seal near the top of the dipstick which fits tight around the outside of the top of the dipstick tube as you insert the dipstick. That top seal may be broken or worn. changing "T" handles would not be easy as it appears the "T" handle is attached to the top of the dipstick "glued" permanently.

Just so I understand better as I've never had a problem with my dipstick (other then its weird readings it gives from time to time)

I thought what I posted is that entire rubber piece- top and bottom. Are you saying there are 2 rubber pieces or seals there instead of 1?

[xlr8nflorida]

[QUOTE=Dynomite;91545]What you show in your picture is the seal for the dip stick tube which fits into the engine block at the bottom of the dip stick. What I am looking at is a rubber or soft plastic (not removable) seal at the top of the dip stick inside that dip stick housing that fits over the dip stick tube as you insert the dip stick.

Makes perfect sense now- thanks :mrgreen:

In my mind I had that all has one unit.:jawdrop:

I knew you would come through with the photos - you always do.

Hey can you post a photo of Dex-Cool for me? :thumbsdo:

So in cars other than ZR-1's, has anyone had this problem. If so, what do you do for a fix and what do you replace it with?

[secondchance]

Well, my 94 behaves similar in that after driving for a while, dip stick will pull up by about 1/4". I think my 91, even when the car was brand new, did the same thing.
I did not pay much attention to this figuring it was pressure build up in the crankcase. I remember reading that design engineers had some issue with high pressure LT5 was generating in the crankcase and resorted to some "creative" solutions.
Am I to understand most other LT5s do not push the dipstick out a little after spirited driving?

[rkreigh]

with the high rpms and all the nice tightly packed whirring parts in the LT5 they have a bit more "windage" and blowing out the dipstick at high rpms isn't at all uncommon

my LSV does it at the drag strip. leak down test will assess the overall health of the engine, and yes, as the engines get a bit long in the tooth a bit of blowby and cankcase pressure is common

put a little spring on it or the seal.

I'm going to do this too, but the only time that happens to me is over 7300 (*so everytime I drive her*) :mrgreen::cheers:

:iamwithst I understand!!

[RiceEatingZR1]

This happens with mine as well. I noticed it earlier this month. did the seal fix it?

Shaun, sorry, I havent figured it out yet. but its seems to be mostly the cap where the dipstick meets the handle that may be worn. but still not sure.

Thanks Luis, if you figure it out let me know, and if I figure it out I will let you know.

hey the dipstick Wayne sent me worked, it stayed in.

just need to find another one. I tried to swedge the inside of the cap on my original stick, but it didnt flare out enough.

Thanks Wayne!!!:thumbsup:

[WydGlydJim]

Mine does it.........
:dontknow:

[FULLPWR]

Mine does it.........
:dontknow:


leave that thing alone and spend more time with the Z gear shifter.....:wave:

[sammy]

mine did it too until i put a small oring on the dip stick now it stays in fine.

[RiceEatingZR1]

is that the Ring next on the block or on the cap of the stick itself? sorry for my stupidness.. :confused:

You are welcome, it all works out. You got plenty time to find a good one with a handle, that stick is yours now. :-D

[sammy]

i had a great selection of the green o rings that are used on airconditioner and hydrolic systems. and found one that just fit inside the tube and then put it on the dip stick and rolled it up to the handle area put the dipstick in the tube and its stayed ever since . no more of finding it 1/.2 in out of the tube . the green orings are made of a better material than the black guys

Hope this helps
