Looks like we have a bad piston and metal in the oil filter. I sort of doubt the aftercooler pipe failing caused that. Thanks for you help on this. Looks like a long block. Russ

There was no black smoke out the exhaust. There was black smoke coming out of the air cleaner. The aftercooler was removed taken apart cleaned and pressure tested. We’ll check those items Monday.

The loud bang was the escape of pressure. We are just going to start that process. Happened on Friday. I am hoping that what seems to be a back pressure is not another bad engine.

Thanks Tony appreciate all your advise. I am going to sell the boat this spring and will fix the engine rather and wait and be told to do it or loss a sale. Looking at a 52 or 56 Carver hopefully with Cummins instead of Volvo.
Regards,
Russ Keyes

Yes we discussed it quite a bit and it is exactly 12 quarts. It did solve the oil being pushed into the air filter.
I’ll send a picture.
Thanks,
Russ

Good Evening – Would seem we are at the end of the trail. Installed your new CVV and still have substantial blow by on the port engine. Puffs out of the filler cap at idle and significant pressure at cruise. The pressure difference at the filler cap between the two engines at the same RPM’s are remarkable. Mechanic is convinced it got hot at some point cracked the head and expanded the pistons and rings. Got any good deals on a 5.9 370 HP? Russ

I have read about and seen the CCV system you have on your tips site. Do you think that is the problem and not blow by. The airseps were installed last winter. The other engine has the same set up and no pressure at the oil cap. Do you sell the system as a set, or is it available else where? It’s worth a try, I’m thinking short block right now. Russ

Both engines start quickly and run well. They both smoke when cold and hardly at all when block heaters used. We were in the process of getting another boat, then this happened. I want to be sure the engine is right before I sell the boat. Is that much blow by OK? What is piston “pick up”. I do have these pictures. Thanks for the reply. Russ

Good Afternoon – Finally completed the requested items. 1.) Drained all oil and added 12 qts. 2.) Marked dip stick at 12 qts. 3.) Checked both solenoids again, Good 4.) Primed injector pump, Started cold engine (5 days) 100% throttle. Started right up lots of blue smoke. Did the same for starboard same result 5.) Did a sea trial engine ENGINE DID NOT DIE! at WOT Good news, Bad news, lots of blow by with oil filler cap off and there was dip stick pressure and slobber. With cap off there was smoke, pulsing, lots of pressure when you put you had over the hole. Compared it with starboard, which had no pressure. You solved the problem unfortunately it seems the underlying issue still exists. Thanks Russ

Good Morning – He is saying 12 quarts not 13 for the low and should it be 14 quarts instead of 15 for the high as the chart shows. Mine is the older pan without the extra baffles and the newer dip stick. The pan currently has approx. 14.5 quarts in it. We sucked it dry after installing the new head put 1 quart in the filter and 15 in the pan. The two sea trials pumped about 1/2 quart out of the breather. I will drain and remark the dip stick as recommended, on both engines. Russ

I guess I am doing a poor job of responding. I have scheduled my mechanic to come in and do exactly what was suggested. I only meant to explain what we have done in the past. I am completely onboard with your recommendations and sure hope they work. Sorry I am more verbal than verse. Russ

We know how much was put in with oil change three weeks ago and with the oil that has come out, filled the new head and the new oil filter we are sure current is 12-13 qts. Did regular the compression test. We will now do 1 & 4 and get back. Thanks, Russ

We have installed a clear tube section in the breather hose to the air cleaner. So we can see what is happening as we increase the RPM. Up to about 1800 RPM no oil, no smoke, at 1800 when the turbo kicks in there is a lot of oil and the engine dies, but will start right back up. On a previous sea trial at 1800 plus RPM at ran a little longer without quitting and there was a lot of smoke before in finally quit. There is a fair bit of smoke on startup, both engines. I am told that is normal. I have block heaters that I use in the winter and the smoke is a lot less when they are used. It would seem we would have to be able to test compression at the higher pressure produced by the turbo to confirm this problem, is that possible to do? I believe I have done what Tony has suggested except the primed start at full throttle. Have I missed something? I would love not to pull the engine. Russ

Finally got the turbo back and in, as you thought it was not the problem. However the turbo did have some issues. Was worth a try because next step is expensive. We are left only with bad rings. Oil level right, compression OK, fuel solenoid working properly. We are very confident the engine quits because a lot of oil gets dumped into the air cleaner when turbo starts to kick in. We can see it happen. Under 1800 RPM runs great. When it does quit starts right up no sign of fuel starvation. Sounds like next step will be to pull the engine. Thanks for all your help. I’ll you know what we find. Russ
