sticky lifter on 3b engine?

[haryv]

Hi all,

I need to verify this and if its safe to drive which I suspect would be the case. I just started up my bj-60 this afternoon. Two things i noticed, when the engine kicked over felt a thump in the frame/body. I asumed it was a loose or broken engine/tranny mount. Inspected the engine mounts seem okay. Need to crawl underneth the vehicle to inspect the tranny mounts.

Problem number two.

After starting the vehicle heard a tick tick comming from aproximatly the valve cover area. It sounded more consistant then just one lifter. Mabey I am wrong but its sound is sharp and distinct. Do these vehicles have hydralic lifters installed? or mabey its a sticking valve? What should be the starting oil pressure on these vehicles when its 45 F outside? I find that it burns less oil in the morning when the block heater is pluged in. The engine has 379km on it and it had a oil change about a week ago. checked the oil after this event and oil is full.


Thanks

Harry

hi,
it could be loose tappets! maybe doing a valve adjustment and at the same time, take a peek at the rockers for wear.

you will feel a lump or two when it miss fires on a cylinder before the head is warm. once it is warm then you don't have it happen. Standard diesel thing.

the valves need to be adjusted a couple times a year. your are probably out of adjustment. do a search for more info. also your rockers may need resurfacing. they are not zero lash lifters. they need to be adjusted. old school

Thanks

see msg above inside

Wow, the valves need to be adjusted a couple of times a year? Normal old lifter adjustments usually are not that frequent. Thanks for the heads up.

Now the thump was comming from the back exaust system. I suspect mabey a broken hanger or as you said a back fire. First time in two weeks it has done this. Other wise its a good truck. BTW, where should the oil pressure gage read when the engine is running? I was sold this truck with the oil pressure gage not working and owner informed me of it. I went to check it today and the wire fell off. Reinstalled wire and pressure gage reads as the top of the white band at the top. I suspect this is the normal range.

dropped a precup?

 

[brownbear]

maybe what I said about the thumping sound is not your symptom.

If you dropped a pre cup Wayne would it not be a total shut down?

Harry are you in Vancouver? If so there is some very qualifed cruiser mechs there. Might be worth bring over to them for some advice. Also there is many cruiserheads in the area that are very familar with the 3b. They might be able to met you for a coffee and listen to the engine idle.....

Hard to tell what a noise could be from a description. Maybe some of the Vancouver or where your from guys could chime in......

If your on the island you could go visit Rob Lassman of Radd Cruisers.

Fully depends on your KMs..... I think if your 15,000kms a year you could do it once.

See your owners manual for the recommended interval.

What oil did you just change it to? Perhaps its too viscuos for the cold weather? Does the tick go away when warm or once oil reaches the top end

I suspect since you had the oil changed and now this issue ,the oil is perhaps too thick ?

Cheers

Once a year with "normal" mileage is ok for your valve adjustment.

Sounds like you have figured your thump: Broken exhaust pipe mount.

The tick? Does it go away when the engine warms up?

I immediately though precup too, but lets hope not. I think it is a precup in Poo, and Poo still runs...just with a bang bang bang every rotation. When I take it apart we will know for sure.

Get yourself a 3B engine manual, as it walks you through the valve set process.

I would not rely on the stock guage...get or go to someone that has a mechanical gauge and get a datum.

.

not nessarily, i have seen 3Bs with complete shut down after a dropped precup and i have seen the top of the piston looking like the moon's surface but still running...

Going to warm up the vehicle today and check the clearences of the valve lash. I HOPE its not a precup. dont have the funds at the time to do major engine repairs.

Try a cold set 1st, just in case something is banging around in there:

COLD
Intake - 0.25mm or 0.010in
Exhaust - 0.40mm or 0.016in

HOT
Intake - 0.20mm or 0.008in
Exhaust - 0.36mm or 0.014in

Out of the Max Ellery manual.

the sound does not go away when it is half way to the warm point on the temp gage. Going to warm up a little more till the temp gage neddle reaches the half way point on the temp gage then check for any loosness in the valve train. The half way point on the gage is the normal running position.

What is the firing cyle of this engine starting with #1 cylinder at the front of the 3b engine? and working to the back side of the engine? I was given a call by a member here and he said its most likly will be a precup that may have come loose. Thats not what I wanted to hear. Anyway I am going outside again and check the valve lash on all cylinders. Will get back with the info in about 20-30 min.

dropped a precup?

Seconded

 

[haryv]

Sound little off but no precup drop..

Had mike who is a cruiser owner come over. he said that it did not sound like a precup but when I was there with him It has that distinct tap sound in all cylinders. A very distinct loud tap but he said its sounded a little off mabey in the injectors but seemed okay. He did tell me that with these engines, as soon as a water hose burst that the head would crack right away. He said that my hoses looked original ie, thay have the same clamps since it was new and of course, I agreed. The hoses are long over due for a change. BTW, he also said putting sulfuric acic in the cooling system cleans out all the crap from this engine. Anyone care to comment on this?

Again, The PO never knew that he had to have the engine flushed untill the radiator started to leak. He has the radiator replaced before I purchaced it.
I have owned it for four weeks now and it has lost no coolant.

Also he said that if the injectors patern is wrong it may crack the precup. So definatly going to take this in to have the injectors taken a look at.

I checked all the valve lash clearences. Alot of them exceed .022 inches so its way over due for a valve adjustment.

As far as the thump in the body of the vehicle when starting, no big deal. the rear most mufler mount broke.

Bring it around to this guy. He does the nozzles for a good price.

He did exchange for me. No down time.
