I was wondering if anybody that has done a cam swap used assembly lube on the cam, or if they just cleaned down the cam with brake cleaner and then poured oil all over it.

Should not need assembly lube with a hydraulic roller. It is generally only to help flat tappet lifters wear into the lobes. I wouldn't think you would want anything other than oil on there.

 

Ok thanks, i'll make sure to just pour a good amount of oil on it.

Redline Assembly Lube is great stuff, dissolves as soon as the oil hits it and has no particulate. I use it all the time, as do some of the sponsors. Oil will work, but won't stay on the cam long.

 

Also another quick question: How much psi should i leave the air compressor at when i go to do my springs. I bought a compression tester fitting so that i could hold up the valves, but im not sure what pressure to have it at because i have heard not to have to much pressure. Thanks

I use GM E.O.S. assembly lube

 

Figure a high compression motor has in excess of 170psi and most compressors don't go that high...so I can't see 100 or more being an issue. When I did the springs on my truck I used 60-80 psi if I recall and it worked fine. You don't want less than 30-40 .

 

I cleaned my cam with brake cleaner. I used the cleaning rod for my .454 Casull to clean inside it (mine has been gundrilled, some I have heard, are not), and then used straight 30W for lube.

I had my air compressor set at 65psi and it held the valves up with no problems.

Not to say the compressor method doesn't work, but, I had one go down on my and leak and you guessed it, the valve dropped. I used the TDC method last time and found it a little easier although I did have the advantage of having a boroscope to ensure the piston was at TDC.
