Dipstick Identity

[Richard M.]

Any opinions about these 2? Pics show dimensions. Research here tells me both are not correct. Each has incorrect features compared to research here in the Archives...Here

Top stick in pics came with a pile of parts. No M or B stamp on it. Notice the cover is flat, no dish down around the edge. It also has a rubbery umbrella that slips over the disk.

Bottom in pic is the one on my '59 270hp that came with the car 28 years ago. It has the stamped "M" up near the top.

Both are missing the felt seal. Note the finger pull ends have different ends too.

p.s. Speaking of DS's, anyone know how Dennis Clark is doing? I miss his one liners here on the TDB.

Hi Rich,

I have the original dip stick my 60. Richard Fortier (sp?) is planning on making a reproduction one that looks more like the originals then the current ones on the market. I sent him several detailed pictures and measurements from mine for his use in fabrication. When I get home tonight I'll post some of those pics for ya.

Re: Dipstick Identity

Here are photos of the dipstick from Bowtie 1960 (the stick on the top) and the bottom is a stick similar to what you have, but not C1. Distance between ADD and FULL is roughly 3/4".

Re: Dipstick Identity

I believe the Bowtie dipstick has a "W" since the legs are slanted; as opposed to the straight legs on the "M" on the lower dipstick.

Good news Mike, thanks for that. Tell him "HI" from me next time, and good health.

Love to see 'em Tom, Thanks.

Thanks Joe, So that one with the little rubber cap is like the one in my pics. And it has the "M" on it. Add to Full is 3/4" too. So this one came with the '61 I'm restoring and won't be correct. I'll have to locate a real one.

more pics of this wrong one...

Re: Dipstick Identity

The stick with the rubber cap is for a 64 and has correct embossed markings for oil level. The "stamped" letters are typical feature on reproductions. I've seen both handle styles and M & W markings on both 63 & 64s.

Re: Dipstick Identity

Pics of my dipstick.............. Doesn't sound quite right............ 1960 283/230. The original is on the bottom. The one I used for comparison is what came with my 58, obvious repop.

Well picture upload doesn't seem to be happy with me tonight so here is a link to them on photobucket.

Top photo: My research in 1991 and 1992.

2nd & 3rd photos: original (GM # 3739830 used on 58-63 Corvettes & Chevy trucks) dipstick from 1959 Chev. truck engine stamped "F721M" (July 21, 1959), casting date "G209" (July 21, 1959) assumed to be the same as a 1959 Corvette (Flint engine plant).

4th & 5th photos: NOS 64 Corvette dipstick w/rubber stopper (GM # 3846810). With the 1963 system, the PCV system was drawing air in through the poor seal at the dipstick. The new design (rubber cup stopper or metal bell shaped stopper) corrected the problem. I have had 1964 Corvette dipsticks with both the rubber cup stopper and the metal bell shaped stopper. I'm not sure which was installed on the 1964 assembly line, maybe one superseded the other.

Thanks Tracy, now I know the one with the rubber cap is a '64. When you say "..."stamped" typical of the repros", do you mean the heavy stamp as in the '64, or the lighter stamp like from my '59?

Tom, more than 4 links and it won't load, and if you keep trying it'll lock out your account, happened to me a while back. Here are a few of your pics....

You said "original" is on bottom. Do you mean the one with the lightly stamped letters? Like from my '59 above? Actually, I keep forgetting, my '59 has a '61 Flint Oct 20,1960 (J200) FI026CU block.

Thanks Guys,
Rich

Dave, Thanks for those pics. I found your diagrams and info in that thread I linked in my first post. It helped much, but I was still unsure of what I had.

So would you think that the "lightly" stamped one from my '59's ('61 engine) is real or repro?

Rich,

Can you spell idiot? I can.... TOM............

The original is the one with the heavy stamping shown as the TOP dipstick. (boy do I feel like a dipstick...........)

I think the pics that others posted support the heavy stamping as the original style text

Re: Dipstick Identity

According to the GM parts book, the dipsticks used in the C1s were also used in the Chevy trucks, series 3-4 (V-8, 58'-59') and series 10-40 (early 60s); part number 3739830. They come up from time to time on ebay for around $300. I have searched salvage yards and swap meets and never found one. I will wait on Fortier to complete his C1 repro dipstick to use in my 1960.

Rich

Rich, When I refered to a stamp I mean a stamp typical to something you or I could do at home. In contrast, the embossed markings are where the numbers have been pressed into the stick. The metal is actually displaced and quite evident on the back side of the stick. This embossing is typical for 63 and 64, but i can't speak for other years.
