I have a 181 - SL55 fuel pump is on the way.
Re: I have a 181 - SL55 fuel pump is on the way.
I am only getting 20psi when it's cold (60). At 70F I only hit 19or so. 18 could be fine if it's hot out. For a leak check I just glued some Home Depot PVC with a cap. Tap and thread a fitting for your air compressor and clamp it on the T/B. You gotta clamp off a couple vac. lines and the 2 PCV hoses (AA battery fits perfect LOL). Slowly pump the engine to 15 or so and listen. Some air will come out the dipstick and oil filler. Use a hose to your ear to listen around, higher than 15psi and my tester pops off the T/B and scares the crap out of you....

Here's a picture of the leak tester I purchased for my turbo diesel. I'm going to neck it down to also use for the 6 if I need to. Definitely cheaper to do the Tuna D.I.Y. method. This tester also comes in a 3" size as well. http://www.dieselsite.com/index.asp?...ROD&ProdID=669

I didn't make it over 5psi before I found a leak on the passenger plenum. I tried to remove the plenum but stripped a bolt head during the process. Also, apparently I cross-threaded one when I installed it so I have that to deal with also. I'll be installing threaded rod (studs) as soon as I find them.
By the way, the bolts were aftermarket hex bolts.

I don't think you will be able to slide the back of the manifold up to the Y-pipe with the studs keeping it straight. Try it though, that is a really good idea. Some chrome acorn nuts, hell even SPIKES would look pretty cool LOL!
Hmmmmmm.........

F#*& it, I'm just going to weld the manifolds in place.

Do you know where I can find the bolt specs?
Re: I have a 181 - SL55 fuel pump is on the way.
I don't know the specs, but would the SS set that Needswings sells work for you?

I have not had any problems with the bolts losening, or the mainfolds leaking, or striping out bolt heads and stuff. You guys are doing something wrong. I am constantly taking these on and off messing with my motor/ fuel stuff.
I use an OEM gasket brand new, every time. I spray the gasket with Copper Seal Spray on each side. Let it dry, then assemble and torque evenly in small steps to 100 inch pounds. DONE!
