Bartman Posted June 18, 2006 Share Posted June 18, 2006 The LT1 fired up almost instantaneously; and boy did it sound mean! I can't believe how quickly it started; I was half expecting it not to start at all (something wired wrong or whatever). I only ran it for a little while because I'm not showing any oil pressure, but it sounds like everything is getting oiled. Meaning no unexpected noises other than a wicked lope. I pre-primed the oil pump and installed a full oil filter to help ensure that the engine would have the necessary lubrication quickly. So how can I know for sure that I've got good oil pressure so that I can run it for twenty minutes or so to break in the cam and change the oil?

Dan Juday Posted June 19, 2006 Share Posted June 19, 2006 Get yourself a $10 mechanical pressure gauge and T it off your oil pressure sensor. I too got a scare one day when I fired up the Blue Bullet and saw ZERO OIL PRESSURE!!! Just the dang 30 year old Datsun gauge, or wires, or fuse block, or some other 30 year old Datsun bit. For me it was easy. I had originally installed a remote oil filter kit so I just uncorked one of the two extra fitting on the filter mount and stubbed a cheap mechanical gauge there. Now if I get a scare I just pop the hood and check the "for sure" gauge. Here's the dumb part. When ever I have the hood open at car shows people are more impressed with the stupid $10 oil gauge than the cool looking tpi motor it's attached to. To quote a local Z bud, "stooges"!

Bartman Posted June 19, 2006 Author Share Posted June 19, 2006 Got a gauge, hose, and tube fittings from PepBoys today, so I'll try to get it installed tonight and give it another shot. It appears there are a couple of plugs over the oil filter boss that should allow me to easily hook it up. Once i determine I have pressure I'll have to record a sound clip as well as take a couple of pic's. Quote Link to comment Share on other sites More sharing options...
LS1 Z Posted June 20, 2006 Share Posted June 20, 2006 I agree with Dan. Put a mechanical gauge on! They don't lie. Quote Link to comment Share on other sites More sharing options...
fastzcars Posted June 20, 2006 Share Posted June 20, 2006 That's one of the reason's I installed all mechanical gauges in my dash. Nice to hear that you got the car going Bartman. As soon as I get my car back I'll be contacting a couple of guys in So Cal to go to Irwindale! Quote Link to comment Share on other sites More sharing options...
deja Posted June 20, 2006 Share Posted June 20, 2006 Yahoo! You'll be out terrorizing the streets of Corona before long. Years ago I ran an oil pressure gauge and idiot light in my 70 AMX because I didn't trust either of them alone. You can't have too much instrumentation.

Bartman Posted June 20, 2006 Author Share Posted June 20, 2006 Well I was able to remove a plug just above my oil filter and install the adapter, hose, fittings and finally the mechanical oil pressure gauge in my engine compartment. This allowed me to leave the datsun sending unit installed around the back of the intake. She fired right up and the stock gauge still showed nothing, but the new mechanical gauge showed plenty of pressure. I let her run for a while keeping the RPMs around 2,000 to help break in the cam and get all the assembly lube into the oil. Tonight I'll change the oil and filter and I'll be able to drive it around a little bit and see how she feels. I'm going to take it easy for the first 500 or so miles to completely break in the cam properly (i think that's what Comp Cams recommends). It really sounds like a race car and I'm sure my neighbors like me even more now. I have mufflers on my dual exhaust, but it's still pretty loud. I'll have to charge up my camcorder and make a little clip to post up. Quote Link to comment Share on other sites More sharing options...

I thought that the LT1's have hydrolic roller cams, they don't need to be broken in as compared to flat tappet cams? Or did you change to flat tappet?

Or did you change to flat tappet? [/quote']It's still hydraulic. I thought I saw in my cam documentation to break it in for 500 miles, but maybe I'm mistaken. I'll check it out when I get home tonight. Quote Link to comment Share on other sites More sharing options...
fastzcars Posted June 20, 2006 Share Posted June 20, 2006 Ya, there are both type's, Hydrolic ROLLER and Hydrolic FLAT tappet lifters. Do you have the lifters in the first picture or the second picture? If you have one's in the second pic, then yes, you do need to break them in.

So maybe I don't need to break them in for 500 miles. Quote Link to comment Share on other sites More sharing options...
fastzcars Posted June 20, 2006 Share Posted June 20, 2006 No you don't. All right!!!!:icon14:Go rip up some assphault!! edit: here's a page from com cams website.

Bartman Posted June 22, 2006 Author Share Posted June 22, 2006 I finally remembered what part I installed that claims to need a 500 mile break-in...it's the stage 1 clutch, pressure plate and throw out bearing I added. I guess I should take it a little easy for a while. Quote Link to comment Share on other sites More sharing options...
