    Hi All, my 1970 GS350 has a messed up dipstick arrangement. i have just bought the car and uncovering a lot of gremlins.. The dipstick has a tube, the tube fits to the block just above the oil pan in the flange. (see below)

    The dipstick tube starts underneath the level of the exhaust manifold (below), its virtually impossible to get the dipstick in. I poked a welding wire down the hole and it seems to bottom out about 16" down.

    The actual dipstick is a joke, its 6" long so goes nowhere near any oil, it looks like its out of a 4 cylinder Ford!

    Can anybody tell me what i need, TA look to do a one piece tube and dipstick for a 350 - part number TA_1500C - this is pretty much the only one i have found that looks remotely right.
    anybody any ideas? many thanks

    Here's what my 71 350 dipstick tube looks like on the engine. I can measure it if need be. I think any 350 dipstick and tube that are a matched pair will work.

    Hi Greg
    yeah, thats what mine looks like, cool, but you can see my dipstick is like 6" long. :-(
    Could you measure your dipstick please buddy, that would be a massive help (distance from under flange to tip)
    thank you pal

    Ta performance has new dipstick . Longer also. With tube . That is not the correct dipstick.

    I beg to differ. That dipstick is a showing exactly full with 5qts of oil after an oil change and start to circulate. Maybe newer ones have the sealed end but this is what a 71 Buick 350 dipstick looks like.

    Every buick 350 I've had had a two piece dipstick. Lower part presses into the block with a light tap, and bolts to the block with a tab. The upper part bolts to the exhaust manifold's heat shield on the driver's side.

    The original on my 71 plus one off a spare 71 look like this. Any style of stick & tube the right length will read the level correctly.
    This rubber coated stick is from a blue year motor....
