adallak Posted November 13, 2005 Report Share Posted November 13, 2005 Guys, check this out but be careful! http://www.cadillacforums.com/forums/showthread.php?t=51792 Would our Guru "approve this message"? That's a big question. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
acklac7 Posted November 13, 2005 Report Share Posted November 13, 2005 I think there was a thread relating to this procedure a few years back..And someone did Hydro-Lock a N*....Blew the side out of the block out!...Actually a dealership in Canada was the culprit....Anyone else remember that thread?

Scotty Posted November 13, 2005 Report Share Posted November 13, 2005 This was the thread, but the photos are no longer retrievable, this certainly makes me reluctant to do this procedure, I had forgotten about this adallak until acklac7 reminded me, Mike http://caddyinfo.ipbhost.com/index.php?sho...98&hl=hydrolock Here was the Guru's explanation to me: (bbobynski @ May 20 2004, 03:25 AM) What's not to believe?? The likely explaination was described above. The tech likely put too much "top engine cleaner" thru the throttle body too fast and stalled the engine with a lot of liquid still in the intake manifold. It started up and idled and as soon as the thru put thru the engine was increased by opening the throttle to drive away one cylinder gulped the liquid and hydrostatically locked. End of story and engine. Link to comment Share on other sites More sharing options...

Scotty Posted November 13, 2005 Report Share Posted November 13, 2005 :0 Nice save Acklac7! Yep that would ruin my day for sure! Last night with no one around on the parkway, I did 10, second gear, full throttle to 70, decel to 40 runs in a row. I can't wait to hear how my engine sounds today, it was running SO increadibly smooth last night. Link to comment Share on other sites More sharing options...
tjtjwdad Posted November 13, 2005 Report Share Posted November 13, 2005 Scotty, I like doing those 40 to 70 MPH burst as well ... you can really feel the torque. But I've often wondered about the stress on the motor mounts. So when I do it these days I give it about 3/4 throttle (in 2nd gear) and then full throttle @ about 55 MPH. All the way to 70, sometimes 75. Oh, when looking elsewhere today I read one of your quotes (regarding talegatters: "if you can read this ... roll up your windows" Link to comment Share on other sites More sharing options...
JIMDTS Posted November 13, 2005 Report Share Posted November 13, 2005 Those wot's do take a toll on the engine mounts I had to have a lower front mount replaced & I'm sure it was do to the wot's. I haven't been doing them too much lately No need to do them since I had the rings & pistons done every time I do them I look in the rear view mirror to check for any smoke so far NO smoke so I drive it hard from time to time and no carbon build ups.So far so good. Now when I do the wot's I just step on the gas slowly in second take it up to redline and caost back down works for me..Every now and then I do kick it in the a-- to blow it out.. The new rings and pistons did the most I have been checking the tail pipe tips looking for carbon I used to have a black soot build up but now none to speak of.. I have seen a couple Northstars that were hydrolocked and had holes in the block Interesting that they still ran banging and clanging away..

Thanks for finding that. I have NO memory of writing that, but I feel it By the way, I don't go full throttle either probably about 1/2 to 3/4 until about 55 then full. I don't need to put that kind of strain on my tranny. I am also conservative like that. I drove my 80 yo grandmother home last night, and she always raves about 'the caddy' saying how powerful, smooth and beautiful they are, there is "nothing like it" she says. After a warning, saying "watch this", I treated her to an entrance ramp WOT to 88 last night, she smiled and said, that's incredible power.....the engine was pulling especially hard last night She endured the WOT very well , come to think of it, better than my wife Link to comment Share on other sites More sharing options...

Yeah, I remember that. Those pics hurt just looking at them. Personally if I had to do that proceedure, I'd pull the plugs, fill the cylinders with liquid and let it set overnight. Then the next day I'd rig up my shop vac to my home made vacuum brake bleeder and suck the liquid out by inserting the 1/8" tube into each cylinder. No chance of a hydrolock that way.

Plus change the oil and filter 'right now'. Right?? Jim Drive your car. Use your cell phone. CHOOSE ONE ! Link to comment Share on other sites More sharing options...
Scotty Posted November 14, 2005 Report Share Posted November 14, 2005 I like that idea better, and I guess it gets the top of the cylinders good, but if I wanted to clean the dome of the head, is there anyway to spray upward to wet the dome? Any ideas? Link to comment Share on other sites More sharing options...
Ranger Posted November 14, 2005 Report Share Posted November 14, 2005 Yeah, I kind of figured the oil & filter went without saying. I guess fogging the cylinder would be the only way to get at the head. That said, I have been of the understanding that the proceedure is for freeing up the rings rather than curring cold carbon rap, thus flooding the cylinder and vacuuming it out would seem to be more efficient to me. Hope I never need to do it though. Link to comment Share on other sites More sharing options...
JIMDTS Posted November 14, 2005 Report Share Posted November 14, 2005 That deep carbon cleaning process is a waste of time IMHO. The wot will take care of carbon problems. From what i was told the deep cleaning process is a waste of time. I had to have rings and pistons for the so called cold piston slap. The rings & pistons cured my problem of high oil consumption and No more cold knocking I actually did get to see my engine when it was torn down and the pistons and cyl. wall,valves and head were super clean..Everything looked like the engine had no miles on it.
