Cyl #4


Spark plug #4

time for comp/leakdown test

I then tested spark. Fun little tool in MS I must say. Played with dwell and rpm.
#4 spark plug is very shitty spark.
All the others were spot on. I increased dwell and it cleared up some carbon and made #4 spark well but the engine still runs like ****.
I should of switched the plug around to test.

Tomorrow I'm going to compresson test ALLOFTHEM and probably replace the plugs with IK22's or BKR7Es that are cut to fit the coils.

Interesting fact: I found another plug to use besides BKR7E's where the insulator and actual end are different. Same 7 heat range but doesn't come out as far. The v8 drag guys use them here.
Here's the part number and link for info. NGK 4091 R5671A-7 Racing Plug

can you please tell me in what universe comp testing 1 cylinder alone has any meaning whatsoever?

do you seriously never do anything properly?

you literally half *** EVERY single thing you do.

lol don't take this the wrong way, I'm not even mad. its just really amusing

Listen here bitch. It was 11pm at night and I wanted to be sure the cylinder has compression.
And **** mosquitos. hard. sideways.

Haha, I never have time for **** these days, nor the patients.

patients?
are you a doctor?

Impuls

iTrader: (1)

I might be.
You wanna ****?

Impuls

I thought so.

So, I'm having an awesome day. Car didn't start now, laptop won't connect to MS, and I'm not liking my compression numbers right now.
I expect the starting problem is from flooded cylinders of seaform so I'm letting them "air out"

Time to a leakdown test.
JUST TO MAKE VLAD HAPPY:

So, it does seem like cyl 4 is a little bit sad... What did the leakdown test show? Or are you just saying it's time for a leakdown test now that you properly did a compression test?

lol I think he called the comp test a leakdown test

he just loves it when I correct all his mis-types and posts

yeah, doesn't look too good, bummer.

I'm guessing that's a low reading tester too, but still doesn't change the fact that there is a 20% variation in #4

did you even do the compression test with WOT?

Impuls

iTrader: (1)

No I haven't been able to do a leakdown test. It's been raining all day here in Tampa and I had to deal with other things.

Impuls

Swapped in some IK22's.
Started up fine. Did some seafoam, and found the manifold/turbo flange gasket blew out. So time to remove that gasket anyways the flanges were already trued so it was kinda pointless to have the gaskets.
Drove the car around and it runs pretty lean anywhere in WOT load, So I didn't do many pulls though.

aren't you supposed to run the comp test with a warm engine?
your rings won't seal as good with them cold.

also, throw in some oil and see if comp gets better.

iTrader: (3)

Yup.

Impuls

What, did you want me to rub the engine till it's warm?
It's probably why the compression numbers were so low.
It runs now but has misfire still going to gap down the plugs more.
Do a warm compression test and get around to this leak down.

About the oil thing.
Supposedly, the Mystery Oil stuff works best to do that.
An engine builder was saying instead of the seafoam(I was using to clear up carbon) use it and it's what all the guys around here are doing. Helps the rings seal or something.

He meant put oil in they cylinders during the compression test to see if it brought the numbers up. ATF works better than MMO if you're trying to do a top end ring soak.

Impuls

iTrader: (1)

Okay that's what I always thought. Using ATF for the rings. I did a dab in each cyl when the engine was built for break-in.

So warm compression numbers are here and not looking any better. :/



Also got a video of the now very shitty idle and smoke out the exhaust(when rpms decrease) meaning valve/seals, correct?

Also have video's of how it doesn't like blipping the throttle or increasing the rpms.

that motor needs to come out and apart.

you blew that engine..
