This is my daily driver K3500 Gen VI 454. It's a stock engine, but many of you here are more familiar with the internal workings of engines than in the truck forum.

The other day, I noticed my truck was ticking loudly going down the road. The truck was cold, but it was more than a start up tick, as a start up tick would have stopped by then. I wasn't sure what it was, I thought maybe it was the PS system since it has a leak, but the sound wasn't really right for that. The sound stopped as I was going up a hill, but my oil pressure was way high. The oil pressure did start to come down eventually, but it still ran about 20 pounds higher than normal all day. I dumped some seafoam in, but haven't run it that much since then.

Researching high oil pressure with Google is pretty tricky since you get either "low pressure" threads, or "oil pressure switch" threads.

This morning the truck is again ticking loudly. The area it's coming from is hard to determine.... sounds like it's coming from underneath the truck if you bend down, but it's loud under the hood too. It's a fairly light, so I don't think it's bottom end, but maybe. I didn't run it long enough to warm up.

I'm thinking, I have a blockage someplace, but where? How can I fix this? I was thinking maybe drain the oil, and fill with a few gallons of kerosene and let it soak for a week?

Might try a new spin on oil filter.

If the filter was plugged wouldn't it simply bypass?

I'm going to get a mechanics stethoscope and see if I can get a better idea if where the sound is coming from.

I'd try a new filter too. It's cheap and simple enough to do it as a test and see if it helps.

I picked one up today, when I went to get a stethoscope... it's just that it's kind of cold and snowy, so I haven't gotten any further than that. I am so ready for winter to be over.

Just don't use a FRAM oil filter, they cause problems, not cure them. WIX is one line of the very best.

I haven't used Fram in years. I did use AC Delco until they were made elsewhere, and then later became a Champion Labs E-core design. At that point I switched to Purolator, although, I read on Bob is the Oil Guy that they can tear...

I finally got outside today.... no flurries. I started the truck up and start poking around with the stethoscope. It only took me a few minutes before I hit the fan :-/

Never having used one before I was having to experiment a bit. I went along each valve cover, touching every inch or so. Checked the accessories and exhaust. I wasn't finding a smoking gun, so I switched to a hose, from the stethoscope. That wasn't getting me anywhere either. For a minute, I though it was simply an exhaust leak, as I noticed my muffler is really starting to leak.

I went back to the stethoscope, with the valve covers, and just about the time I thought I was finding a louder spot, it stopped ticking. The truck had warmed up enough for it to go away. I'll have to try again later.

obviously you can,t cure a problem until you've isolated the cause
I'd try to locate what side/cylinder bank, the noise is on first,then pull the valve cover on that side, and while its ticking at idle press your palm down on each rocker, youll both hear and feel the change in the sound once pressures applied to a worn rocker, if thats the source, chances are good its a worn or burnt rocker, or lifter

IF YOU CAN,T SMOKE THE TIRES AT WILL,FROM A 60 MPH ROLLING START YOUR ENGINE NEEDS MORE WORK!!"!
IF YOU CAN , YOU NEED BETTER TIRES AND YOUR SUSPENSION NEEDS MORE WORK!!

I think it's the driver's side, but I'm going to recheck that since it stopped while I was using the stethoscope.



I just started it up after sitting several hours and it didn't tick at all. I'll have to wait until it's sits over night, I guess. Maybe that Seafoam is loosening things up. The other day it was ticking again after cooling off a few hours.

How much oil will be flying when I do that?

I need to change those gaskets anyway. They've been leaking awhile.

you have options , you can cut a 10" tall and 22" wide section of cardboard , or thin flexible aluminum, sheet metal, to stick in between the lower outside block valve cover gasket rail and rockers, too deflect oil while, inspecting or adjusting the rockers or you can modify and old valve cover

Pretty sure I have one of those nice factory cast aluminum late model big block valve covers, single one without a mate, sitting around here if someone wanted to cut a big slot into it.

if you or anyone else has a single orphaned, tall cast aluminum BBC valve cover,or even a tall cast aluminum sbc valve cover,
yes the tall versions tend to work better in this application, that might care to sell it, reasonably let me know what you want for it,
Ive owned several,of both versions , but they seem to "get borrowed" and not returned rather regularly

(GENERALLY YOU'LL FIND DEALS ON SINGLE VALVE COVERS AT SWAP MEETS AND YARD SALES)

Mine's not tall unfortunately, it's the stock cover. It's actually the extra one out of a pair I am pretty sure originally came from 454cid himself...I bought a 1995 3500HD 7.4 that had one cover cracked along the gasket rail, so he sent me a pair.

Well today, I went to recheck the engine with the stethoscope, but the loud ticking has stopped. I'm guessing it was a sticky lifter and the Seafoam loosened it up. Oil pressure I think it still a little higher than normal, running down the road, but I'm seeing 20lbs hot idle now, which has been normal for this engine/gage/sender.

The oil was changed several weeks ago, after way too long, and I'll change it again in a few weeks after than that Seafoam has had more time to circulate.

Should I still pull the valve covers, or am I good to go as long as the loud ticking is gone? I do need to change the gaskets, but I'd rather wait for a bit warmer weather....it's seems to be hanging in the 30's now.

if the ticking's gone I'd add a quart of MARVEL MYSTERY OIL to the engine and drive it until you have the time to look into the potential issue later, M.M.O. has a lot of crud/sludge solvents and detergents that will further clean up that engine internally given some time, you might want to change oil filters to remove enough oil too allow the room for that quart of M.M.O. and by now that current filter has accumulated a bunch of crud that is best removed from that engine.
that seafoam may have broken loose enough sludge to partly clog that existing oil filter in less than 4-5 hours run time.

Just my paranoid self thinking but since he's already diluted the oil a little bit with SeaFoam, I'd do an oil change before adding any MMO. I'm not a snake oil guy but I do believe that MMO is beneficial in situations like this. A quart in there with a fresh oil change (and then another regular oil change soon afterwards) would probably do a lot of good, but I wouldn't mix it with the old oil/SeaFoam combination that is already in there.

Well actually it's already got a quart of Marvel Mystery Oil in it.... sort of. I changed the oil in late January or early February and added it then. I say sort of, because I have to add oil as it leaks/burns.

Last night, I added probably a quart and a half of oil, as it was already down a quart when I changed the filter...I guess I forgot to include, in my post last night, that I changed the filter yesterday.

It's snowing again today... not a lot, just enough to be depressing/annoying.

So, oil pressure came down and ticking stopped after changing the filter? Sounds like you found the cause of the problem.

No, the filter got changed afterwards. I simply went ahead and did it since it had been recommended that I do so, and I thought it was a good idea.

Clogged filter might have higher pressure up to the point of bypass and then the gauge will see the bypass pressure as the oil is allowed to flow free. Higher pressure at the filter means lower flow to the parts. Reading high pressure to the filter is not high pressure to the whole system.

Usually I start out with Rotella, but lately it tends to be a mix of the cheapest oil I can find, because I've got to add a quart quite often. When I changed it two months ago, I used a store brand made by Warren Oil (5w30, conventional). I also add a quart of Marvel Mystery Oil.

Well, I guess that depends on if you think Seafoam has any effect, I guess. I added a little over half a can the day after I noticed the problem.

I wondered about that, but I'm not familiar enough with the oiling system to know where the pressure reading comes from. I think my sensor is behind the intake manifold someplace, but I can't readily see back there.

On your generation of big block the sender is at the top of the block but below the lifter valley wall - pic from a 1996 Vortec 7.4:

I'm not that sold on Seafoam. On another board for motorcycles, one discussion was of plugging of air correctors jets, and oiling system passages when it wasn't completely cleared out.

I just treated my 1991 Toyota V6 to a fuel system bath on car, Berryman's Chem-Tool fuel treatment, no Seafoam.

Others have had great results with Seafoam in oil systems, not me, though.

I don't recall if I've ever put it in the oil before, I have tried it in the gas, However. I don't know if it did any good. I've dumped old kerosene and old mower gas in my tank with plenty of new gas and it's not noticeable. I decided to try it in the oil in this situation because it gets recommended so much. I think it worked.

I do need to install new intake manifold gaskets this summer... what are your thoughts on changing the lifter at that time, as a preventative?
