Hmmm. Who here thinks ints an absolute necessity to replace the oil pump with cam swap? Does anyone know what oil pump came on a 2005 LQ4/9? My pressure all last summer was great. 45 at idle and it would peg the gauge at 80 at WOT. Im just starting to pinch my pennies I suppose. Spending too much money. Oil a must, under the category of "cheap insurance", or have some of you gotten away with a good stocker?

If I were to do it myself though I'd probably spring for the ported and shimmed LS6 pump just because I'm already in there. For an extra $120 or so it's just something I would do.
But since my wifes car turned out fine with 24,000 miles since the cam/no pump change I wouldn't say it's necessary.

you only have to worry about oil pumps in the early ls1's from what I have read.
you should be in the clear, sounds like you got plenty of oil pressure.

$160 is too much.
Replace if you can. If not...you are probably okay.

It would make sense to me that prices should go the other way since the economy is supposed to be in a slump. I would think businesses would be trying to get the business in,,,not chase it away.
But anyway it will give you piece of mind knowing it's done and you won't have to worry about it down the road.

Well the new cam is in. Swap is going great, what a piece of cake. I had the new cam in , in about 6-7 hours. Drinking beer and anwering GF's phone calls. The pulley fought me like a mother. Mainly because I didnt buy a longer bolt. I cheated and just cut the washer part off so it wouldnt catch. After that is was milk. Anyone ever take the radiator out solo? That was a mother***. I could have used a hand for sure. Well the cam is in, Tomorrow I am changing the springs and PR. Anyone ever check PTV with a dial indictator? Thats the way I am going about it, but I am wondering on how to find TDC with the heads not coming off. Spark plug hole? Cant wait to fire her up for the first time, she probably wont run worth shit. I need to get on my tuning game.
Thanks for everyone help on here.
Orion and Mark, thanks for helping me learn to tune, Some really good people on here.

So who has done then withOUT the aid of a degree wheel to find exact TDC. Also to find 15* BTDC and ATDC Did you just kind of wing it and stick something threw the spark plug hole to find rough TDC?
