TURBO'S to do list (MonyRunner)

[unclejpl4x4]

it's late amd im :bozzer: so i have not read whats going on but  harbor freight pneumatic spark plug cleaner works great

[TURBO]

napa told me the plugs were "pre-gapped" i'd have checked it but wouldn't cha know it? i took that think off my keychain now i cant find it

[TURBO]

cyl #4....

[TURBO]

cly #6....

[Duffil]

if those bujias were de platino then that is correct. adjusting the gap isn't secessary as it is factory preset.

[TURBO]

I've benn good rebletoy83, but i'd be a whole lot better if my truck started working all of a sudden...

lol go figure...too bad it only lasted 2 minits

[TURBO]

what if i take the cat off??? if it runs good, dose that mean i need a new cat?

[Duffil]

yes. if you pull it off and things change then the cat is plugged.

[TURBO]

ok, i give.... no more tonight.... i'll get an early start tomarow when i can get NOISY!!!!!

[Duffil]

you can drill a small hole in the exhaust just ahead of the cat and hook a pressure/vacuum gauge into it. start the truck and rev it up; if the gauge pegs, the cat is plugged.

[TURBO]

how pluged would it have to be??? cause wen i took that vid, there was definately exhaust comeing out of there.... hott too... (duh) but i dont get how it could be "pluged" and still flow. is there like a certain presure it takes to kill the motor??? idk... sounds like what mike said...

We need to find out if only 1 plug looks like this, or all of them. You either have a badly leaking injector, a dead cylinder (no compression), or you have an overall ignition problem. I'm guessing it's an overall problem and they all look like this...

[Duffil]

if your manifolds arent glowing your probably ok, have you checked for any codes tim?

that makes about as much sinse as wipe'n befor ya poo!

[Duffil]

really? explain this one to me. that's pretty strange since that's how the exhaust shop in town will test a cat. I beg you to lay your knowledge on me, master.

[Jud]

If you read the whole post it sais "if the pressure guage needle pegs then the cat is plugged, If not it is flowing correctly".

[Installer_Joe]

tuff crowd tonite. sory, pls cary on

[Duffil]

tuff crowd tonite. sory, pls cary on

nonono please explain how i am wrong. obviously I am not as intelligent as you because i wipe before i poo so please help me out here.

ok i just read the whole thread sober     I would still clean the plugs  with a spark plug cleaner  are they NGK Spark Plug: Plug No. BKR5EIX  ?  i was thinking about geting a set...

well I see it like this bro  if its the original cat and its a 89 how many miles on it? , time 2 throw on a magniflow . 

Now im not a big fan of  throwing parts on and seeing what happends  I would like 2 see you finger this out.  That test here above mention i have never done but sounds like a plan 2 me.   

[BigMike]

But remember, if there is excessive fuel being dumped into a cat, it is possible to overload the cat and leave deposits across the combs. If these deposits never burn off in the future, then the cat would effectively have less useable surface area to combat pollutants.

You would be just fine removing the cat to see how it runs, if this is a concern. A simple compression check will yield the data we are after here.

Even if the cat was plugged and an exhaust valve had yet to burn or warp, the engine would be running just fine, which it's not..

[Caboose]

TURBO is the best driver i know...

[TURBO]

yes Cabosse, i know you've told me before. let's try and stay on topic ok?

COMPRESSION TEST RESULTS:

cyl #1:   175
cly #2:   175.5
cly #3:   176
cly #4:   175
cly #5:   175.5
cly #6:   176

[BigMike]

COMPRESSION TEST RESULTS:

cyl #1:   175
cly #2:   175.5
cly #3:   176
cly #4:   175
cly #5:   175.5
cly #6:   176

Therefore it's not your timing belt somehow jumping a tooth and it's not any burnt or warped exhaust valves. Check these off your trouble shooting list. Nice work! Your cylinders are very consistent!

[TURBO]

sweet now i really dont know what to do

Have you tried walking on your hands? Then you can use your feet for high 5's, eating sandwiches, y'know... the important stuff.

[93tonkatoy]

If the engine and valve train are not the problem, then I would start testing the sensors on the engine that tell the computer what is going on. Somewhere, it is getting a wrong signal, and running the mixture too rich. The FSM has detailed test procedures for them.

Hmm..... those #'s are so close I'm a bit skeptical there Tim.. My compression tester only reads in 5 pound increments.
I gotta ask the dumb question......

Are you bleeding the pressure back off to 0psi between cylinders?

[TURBO]

yup... in fact there is a quick disconect that bleeds all the pressure out even if you doont push that little bleeder valve button.... and besides that, the gauge returned to zero every time i took the gadge off.....

but on the other hand,

i am no mechanic, and i have not preformed a compresion check sence highschool auto class.... but, i am confadent it was done corectly...

but i have ben wrong before

[TURBO]

yeah.... these myserious creatures have eluded me for quite some time now....
