Is it time for a rebuild? part 2

[NEK5]

Alright guys..It`s been previously stated that I`ve had some issues with my motor, mainly that it smokes alot and burns a good amount of oil. So far I`ve done a few things. 1) found out PCV port was clogged on the TB 2) pulled the TB off, cleaned it up, then reinstalled. 3) I then replaced the PCV valve, along with giving it an oil change, and as soon as i pull out of my driveway to take it for a spin, I left a nice cloud of smoke infront of my house, and again every time I got on the gas, or left a stop sign.

I`ve yet to do a compression or leak down test.

As I was told by ryoken to check my blowby from the breather, but I`m not sure how to describe it..like how much is too much etc..

Any suggestions, advice, etc. you want to add, feel free...

If you think it`s obvious I need a rebuild, maybe throw out an idea of what I should do, ie get a rebuild, get a crate (any specifics, under $2k), etc....

Do the compression and leak down tests before you get too involved with replacing this thing.

do a compression test. its a good place to start. If you can do the labor on a motor swap, then $2K gets you a nice motor. I had one built for $1600 that puts out 400 lb/ft. I did a lot of work myself. I did all the engine disassembly.

Well, I`ll be able to get a good amount of help with the swap if need be. If thats the way things go, I think 2k will be my limit, maybe 2500.

I`ll look into get a CT done soon, hopefully my friends dads up for it

you can do it yourself it just takes longer.

ok, yesterday when i was out driving i got the noise again. Sounded more a like a knock, and it did it 3 times in a row, and when i heard it, i looked in my rear view mirror and saw some pretty smoke pouring out of the exhaust

Merry christmas honey, I spent all the kids present money on a new small block.

DO THE FREAKING LEAKDOWN TEST ALREADY!

 

[gmc4cw]

If you keep doing the same thing and expect a different result then, you sir are stupid. Diagnose it with tools, not a keyboard. time to get your hands dirty.

 

[NEK5]

No, I don`t think repeating my self many times is going to tell me anything different. I do plan on a leak down and compression test as soon as i get the time/tools/help. I just got done moving houses, so its been a little busy around here.

As soon as i do both tests, I`ll post up any and all results....I think its not going to be the results i`m looking for, if so, i may have a lead on a motor with the same amount of miles on it, but it doesnt smoke and it runs strong, according to muddybuddy

Since it`s already obvious I`m burning oil, would you rather a leakdown test or a compression test? or will i pretty much get the same results?

 

[beater_k20]

the leakdown test will tell you more information.

it will tell you if and how much compression you're losing, as well as where you're losing it.

as far as simplicity goes, the compression test just tells me that the certain valve is bad, right? not just rings?

also for a leakdown test, what do i need to buy, the fitting, a certain kind of guage?

check this out. it is a simple explaination. a compression test is easier, but a leak down will tell you more. a compression test will tell you if you have a bad cylinder. if you do a compression test and gets some real low numbers on 1 or more cylinders then its obvious something is wrong. if they are all close to the same then a leakdown is the next step.

thank you sir, that`s what I was thinking...

Since I know I can readily get the compression tester, I think I`ll do that first...then if the numbers aren`t too bad, then a leakdown test will follow...

a compression test will tell you NOTHING but the fact that there is low compression in a certain cylinder.

a leakdown tester...
