yeap, but that's doesn't mean on compression stroke

MoparMad, I am looking forward to your next "tip" (please hurry!). EDIT & I am being facetious, it's all good brother.

what is the issue? Trying to figure out compression stroke?
I remove the #1 plug, insert a long piece of copper wire and watch it as I turn the crank bolt. I'm not building rockets in my garage.

That takes to TDC but its a 50% is the compression stroke chance

Take off oil cap and watch for the intake valve open (Slant Six).

I turn the crank while looking thru the window at the pushrods. When the intake valve closes on #1 I know that I'm coming up on the compression stroke.

Sorry about all caps. I know some people are sensitive. But some of us can’t see well so we use all caps. My tip was just to help someone out. Also you don’t have to remove anything but the spark plug. I was also using this tip on a complete engine in a vehicle, not half apart on an engine stand. I didn’t put down anybody else’s tip. I guess I’ll try my best to be less helpful. Not in my nature but I’ll try.

Really?!?! I never met a Mopar owner that was judgmental and ignorant till I joined here. They are usually some of the nicest most down to earth people I’ve ever met.

That’s the plugs there

Welcome to Moparts, where sometimes it looks like you are going through an initiation process in a street gang.

After enough punches in the face you either make it or you give up.

I’ve been jumped by 5 guys, beat over the head with metal chairs and stabbed in the back. That was easy compared to this. Lol

Don’t take these mostly old farts personal. It’s winter and the vast major of them are grumpy old Gus’s. I’ve been here for quite awhile and have had good interactions with most but some here just like to antagonistic. Some jobs have a phenomenon that’s called “eating their young”, nursing, the fire service etc. this place is not different. And you don’t have to be physically young just new “young”

The collective (25K+) knowledge of the Mopar heads here is off the charts (I learn here every day). In fact where I am at knowledgewise is a direct result of being (on) here for 16 yrs.

i HAVE to rely on those here because i keep "loosing" what i used to know !

Hey, the title says top dead center, it doesn't say about compression stroke. But the hint was to find the top of the compression stroke.
Thanks, pardner! I never thought of that.

There are two things one might want to check:
1. Where is TDC? (is my harmonic damper and pointer correct?).
2. What stroke am I on? (top of exhaust stroke or top of compression stroke?).

The OP's trick was good for #2. The piston stop method was good for #1.
I don't worry about what if the plastic plug sucked in because it'll burn up sooner or later. Same with the little paper ball. We don't always turn the engine over with the cam, lifters, pushrods and rockers installed. I've had my finger sucked partway into the spark plug hole. The whistle is nice but I have never seen one in a store.

OP, the occasional snarky reply is what you pay for being in on this outstanding accumulation of wisdom.

R.

come on , just screw in the compression tester and be done .

I look at the dampner.

once again... that's a TDC mark but not on compression stroke necesarilly

Half the moparts members need to go to the top dead center school. So they know what it means...

There will be suction. Depending on what your using for the plug, and how it's being turned over will determine how much suction and if it'll get sucked in.
