My car is a 1967 bb. it says that that 5 quarts are correct and when changing oil filter to add 1 more (total is 6). That is exactly what i did. But the dip stick reads prox 1 quart low. So i added a 7th quart and that was the deal for the last 8 months or about 500 miles. It shows after 500 miles just where it did immediately after the oil change on the dipstick. Now again i change the oil and put in 5 quarts and also a 6th one as i am changing the oil filter again. It reads low..so i start thinking...why? I don`t have the correct dip stick so i buy a correct pink tip dipstick from Paragon...stick it in and it still shows low. Anybody got any ideas? I don`t what to put too much oil in but it concerns me that it reads low.

Re: how many qrts of oil to fill 6 qrt capacity sy
i have been considering that.....damn near everything on the car is either original or numbers match..but i don`t know about the oil pan with certainty. How can i tell if the oil pan is correct as i don`t see it addressed in adequately in any literature i have. Does it have a part number, where and what is it. If it is a larger oil pan am i wise to leave the oil at 6 quarts anyway or add to the ok line on the dipstick?Comment

Correct tube for installed gage?
Does it have the correct dipstick (GM calls it a "gauge") tube?
According to my '77 vintage parts catalog the service tube for all 65-74 Corvette big blocks is 3981089. No length is given, however a footnote says:
"When using 3981089 in place of 3870324, 3981088 gauge must be used."
And a footnote for the 088 gauge says:
"Must be used with 3981089"
The 088 gauge dimensions are:
seat to full mark - 23 13/64"
seat to add mark - 24
So what are the corresponding dimensions on your gauge?
It sounds to me like there was an early tube (324) and gauge (p/n unknown) that was replaced for service with a later production tube (089) and gage (088).
Could be that the later tube is longer so if you use it with the early OE gauge, the oil will read low even though it is full.
Someone with a mid-sixties parts catalog might be able to verify that there was an earlier tube (324) and gauge and maybe the lengths are mentioned.

Re: Correct tube for installed gage?
Clem the '67 parts book lists (group 1.516)the 3870324 tube as:
65-66 Pass. Corvette (396, 427).
There is a listing for 67 Pass. (396, 427) 3899640, does not mention 67 Corvette. Although the 67 small block is listed:
65-66 Pass. Corvette (283, 327)
67 Corvette (327) 3876784
There is also a separate listing for '67 passenger small block.
Gauges
A B
65-66 Pass. Corvette (396, 427)
67 Corvette (427) 17 13/32 18 1/8 3860316
A= seat to FULL
B= seat to ADD
There is aalso a listing for:
66 Pass. Corvette Sp. H/Per. (427) (chrome) 3860318 with the same dimensions

Re: Correct tube for installed gage?
From the 1953-1972 Corvette P&A Catalog P&A30B the 1965/1968 396/427 gauge part number 3925520 is 17-13/32 in. seat to full, 18-1/2 in. seat to add. No corresponding tube part number or length is given but the replacement tube and gauge are specified same as Duke gave with the same notes.Comment

Re: Correct tube for installed gage?
my new replacement guage from paragon is 17 11/16 from seat to add and 16 15/16 seat to full. The separation from add to full of 3/4 (48/64) is not significantly different than the 51/64 in the dimensions provided in your response. It is also not significantly different from the add to full dimensions provided in the string of conversation or the string provided a couple days after this one which you probably have seen. However, the dimension you provide of prox 24" are puzzeling to me as that is 6-7 inches longer than my guage.
Now i don`t know exactly what i have as there are no part numbers that i can see on my service tube or guage. In the posting below this one Dan shows some dimensions for a 67 corvette as 18 1/8 and 17 13/32. Now if had had a guage with these dimensions my oil reading would show 7/16 closer to the full mark (18 1/8 less 17 15/16). Maybe this is the answer but then why would paragon sell the guage with the dimensions i just received...or is there a problem with my tube length. As a side note the guage i just purchased is exactly the same in dimension to add and full mark as the incorrect one i replaced. The new one is 1/16 to 3/32 longer overall length. The replaced one has a green tip instead of pink..i wondr what the green tip goes to.
I still don`t know the length of my tube but may measure when i put the car up in the air again ..but that may tell me nothing as i have nothing to compare it to. Although i can`t say with certaintly that my oil pan is correct i would place high odds that it is. I am not aware of an oil pan that would be 6 courts instead of 5 anyway. When my car is at the regional judging in a couple weeks i will ask them about my oil pan.
I remain puzzeled.Comment
