the one your looking for is the 4l60/4l60e

ps its a PITA to fill with it but it is nice not to have to screw with the oem unit.

your oem unit did you bend both the bottom and top curve over harder?
is the fill point of the tube to the pass side of the brake booster? (not in front of it)

 

[1quick]

yeah it fills right next to the booster and almost all the way up aginst the firewall, the dip stick stays in the trans but the bushing works its way up then it leaks all over, left a quart or two in the gas station parking lot this morning on the way to work lol, the first fucking time i decide to drive it someware, im having a hard time geting the rear powerlog to seal up also, you got any tricks up your sleve for that ive taken all the hot pipe off 3 times adjusted it and its still leaking on the rear crossover flange

 

[Turbocharged400sbc]

its just a shitty flange design, you might be well off trying to install it witht he front and rear manifolds bolted on but loose (you are using the oem MLS exzhaust gaskets right?) so you can shft them around while installing the crossover.

when you put ht erear together and start to snug it up with a new donut doees the front flange (sans bolts) pull outta alighnment? this would point to your missalignment and show ya which way to move the rear/fronts to get em to line up.

barring that, lots of copper rtv

 

[Mook]

pretty sure I have an unopened one sitting in my garage.

 

[Turbocharged400sbc]

lokar?
well shit sell it to this poor bastard so he can at least fix one of his leaks

 

[Mook]

ill check when i get home. i bought it for the daytona and we didnt have to use it.

yeah i have stock manifold gaskets, the flanges bolt up nice and straight its leaking out from under the colar on the cross over side flange, will have to try the rtv

ill take that off your hands if you have the one i need

for that style of gsket the only good way to rtv it is to pull it off and with a new donut youll coat the Xover tube with rtv in the sealing spot, slide the donut on, and then coat both sides of the gasket conical faces.
the oem flanges do a good job of wedging the donut smaller as you tighten em but the zzp flanges dont really taper well enough to help crimp it on but with the rtv on the faces lubricating it they should crush it to the smaller ID its supposed to crush to and then it will seal witht he rtv filling any small gaps

Ill give it a try this week and see how it goes

 

[Turbocharged400sbc]

the oem flanges have a nice rounded curve to the point where it hits the donut where all the zzp flanges ive seen its just cut at a 45* taper so it cant compress em as ewell as the rounded oem face

Oem exhaust manifold gaskets are better than the felpro ones?

 

[1quick]

ive never used the felpro ones, but the stock ones can be reused over and over and still wont leak

yup, plus less $ and headaches

ive never used the felpro ones, but the stock ones can be reused over and over and still wont leak

oh they can leak, but a little care and they will last longer than the car

the only problem is the two layers are spotwelded together and once a pair are first removed from an oem stock motor grit/carbon/oils from the edges manage to migrate in between the layers. so pull em of and squeeze the layers tgether as you use a razor to remove the carbon/wipe it down, then you can blow/brakeclean em off and not worry about the wee bit that does get into there...after a few uses and on jobs where sealing is no1 (turbo cars with high exhaust primary pressures) i grind away at least 3 of the spot welds and clean em and sometimes copper spray em.

fel pro's are fairly cheap but having to scrape off that graphite material anytime you pull a manifold off, makes the oem stainless mls gaskets worth the time since if everythings clean you can just slap em back on in most cases

this is where i point out that the best time to blow/clean a motor is prior to service...sure beats masking shit off and usually prevents crap from around the injector holes from falling in when you pull the rails

 

[ProjectGTP]

I think I have some oem ones laying around. I will clean them up and possibly copper spray between them. I remember seeing that done before. Sorry for thread jacking quick98

 

[Turbocharged400sbc]

sometimes its easiest to grind the spotwelds (look for tiny dimples)

Ok for sure. Thanks

I might have to look into this flexable dipstick. I dont know how mine does not just fall out because the little bracket is broken.

 

[RICH17]

Brian as the 4L60 one from lokar on his L67 car. Very nice piece. It comes with a little tube to help filing the trans easier.

 

[smug]

How does this dip stick stay in the trans? The OEM one has that bracket that is bolted to the trans case but I do not see anything like that on the Lokar.

 

[RICH17]

IIRC It has two orings and its a tight fit. Other than mounting the upper portion to something, which he hasnt done, its been fine.

 

[Turbocharged400sbc]

yeah it is 2 orings and a tight fit, the upper mount is good enough all you need is to bolt it to a piece of sheetletal with a 10mm hole drilled in it and you can bolt that to the master cylinder bolt as i did with the turbo regal

 

[BrianG]

x2 on the Lokar being a nice piece. It's a spensive one for just being a dipstick, but its great and runs right near the rear header with no issues. I do need to mount the bracket at the top soon and between the tight fit into the trans and the top bracket being locked down, the braided line becomes pretty rigid. FYI, there's a flat side on the hex fitting at the end of the dipstick that goes into the trans thats larger than the rest of the sides of the hex at the end. The large flat side goes up against the trans. You'll know what I'm talking about when you see it.

is it possible that my trans dipstick bushing is worn out, i zip tied the dipstick so it can't move and the bushing still slid up an inch, i guess ill order the lokar today I need to fix my trans leak issue before tuesday, also the exhaust is still slightly leaking with a new doughnut gasket rtv'd in there
