They cost a good bit of money….I hope some of the “big dogs” as I like to call them that i mentioned earlier will chime In soon. I have access to an automotive leak down tester. Not sure if it is compatible with this engine though. Do you think one of those type will work?

Joey Mack Posted February 20, 2022 Share Posted February 20, 2022 yes. as long as it seals to the coolant filler neck.. the fluid will change color if exhaust is detected.. yellow or purple.. just follow the directions... jojo Quote Link to comment https://www.bigmacktrucks.com/topic/69251-compression-test-with-tech-tool/page/3/#findComment-489850 Share on other sites More sharing options...

Onyx610 Posted February 20, 2022 Share Posted February 20, 2022 (edited) I found a spot where they are in stock if you wanted to get one. I’m not sure how far you want to get into this. You said you already bought an in frame kit… Edited February 20, 2022 by Onyx610 Quote Link to comment https://www.bigmacktrucks.com/topic/69251-compression-test-with-tech-tool/page/3/#findComment-489858 Share on other sites More sharing options...
Onyx610 Posted February 20, 2022 Share Posted February 20, 2022 (edited) You can’t do a leak down or compression test without that adapter anyway.

Dan107 Posted February 20, 2022 Author Share Posted February 20, 2022 Some may not like this, but I found a "heavy duty" diesel compression tester at the Harbor with a Volvo adapter. I'm going this morning to pick it up. For someone like me, this may do the trick. Don't hate! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69251-compression-test-with-tech-tool/page/3/#findComment-489878 Share on other sites More sharing options...

No EGR cooler on this one...it's deleted and a I fabricated a crossover tube to take care of the coolant flow. It's a deleted engine, has been for the last 4 years.

Onyx610 Posted February 20, 2022 Share Posted February 20, 2022 (edited) Now Im a little more worried for you that it’s deleted….A good amount of deleted trucks have eventually gone through some kind of major failure. Usually in the head. Not all just a fair amount, hopefully not the case for you.

Usually in the head. Not all just a fair amount, hopefully not the case for you. I was aware of this before the delete. When looking into it, I found if it wasn't done properly, there was a heat problem and sometimes head/valve failure. "Supposedly" the provider for mine said it wasn't the case with their software. As I said, I have been running strong with this truck for years after the delete. While it is possible, the way I have mine set up, I don't think there is a heat issue related to the delete. But, one never knows. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69251-compression-test-with-tech-tool/page/3/#findComment-489892 Share on other sites More sharing options...

Popular Post fjh Posted February 21, 2022 Popular Post Share Posted February 21, 2022 (edited) So that could would likey be rings how ever have you done all six are they the same? Did you listen at the exhaust stack? these have a small issue from time to time of a piece falling out of a valve! some leak by would be expected on a hi miler engine! .Seems like the direction here has changed a bit? Are you still looking for air / combustion in the coolant? this symptom useuly reveals itself after or while pulling symptoms of hard starting sometimes accompany it As the cup moves up from its seat or gets cracked ! Being deleted there is a ( higher ) possibility of a cracked head ! just sayin!

Popular Post Dan107 Posted February 22, 2022 Author Popular Post Share Posted February 22, 2022 #1, #3, #6 are all scored! I did do a leak down on the other cylinders (#3) and the only place I could hear air leaking from was the oil fill tube. I pulled the pan before pulling the head and used soapy water to spray up along the bottom of the piston and cylinder....bubbles, bubbles, and more bubbles. Anyway, the head is pulled and I will start pulling sleaves and pistons tomorrow. I'm also going to take the head and have it checked while it's off. I want to thank all of those that helped me here, @fjh, @Onyx610, @Joey Mack you don't know how much it has helped being able to bounce things around and get suggestions. Thank ya'll! 3 Quote Link to comment https://www.bigmacktrucks.com/topic/69251-compression-test-with-tech-tool/page/3/#findComment-489973 Share on other sites More sharing options...
