Pleasurecraft lifter question

[r2d2a]

I have a 1987 v-8 Ford Pleasurecraft and am going to do the lifters on it. I've done plenty on GM Mercs but am a little nervous about going and doing it on a Ford. Mainly because I don't have specs and am not sure if there is a difference with valve adjustments. Other than that I am assuming it is pretty much the same. If anyone wouldn't mind to guide me along that would be great or if anyone knows what service manual I can get for this that would be good too, thanks.

Re: Pleasurecraft lifter question

You do need the manual. But I know many of the Ford rockers are simply the type that torque down, instead of adjusting.

Ok, I'm used to the other kind. I'll start tearing it down in the morning and see what I find.

try to tighten the lifters. If they are all the way down you have your answer.

I wouldn't know what to actually torque to though, I'm assuming there is a specific torque other than just make them tight but I'm not sure as I am used to the other kind. Let me know.

Why are you replacing the lifters anyway??

Re: Pleasurecraft lifter question

The lifters started to get very noisy.

Ayuh,... That's usually a Symptom of other Problems...

Have ya done Any diagnostics at all,..??
What's the oil pressure runnin',..??
Any driveability issues,..??
Done a Tune Up, 'n Service lately,..??

The lifters started to get very noisy.

Along with what Bond-o asked, was it noisy at idle and in neutral at higher rpm or did they get noisy under load? Could the noise be pinging from detonation or preigniton?

Re: Pleasurecraft lifter question

Thanks for the help so far, I'll do my best to accurately explain what is going on. The tune up and oil change were both done in October (boat used all winter, doesn't sit). Both the oil pressure and temp were fine even when the noise occurred. As far as driveability issues I'm not 100% sure as I quickly lowered the rpms and docked. Low rpms seemed fine driving but not sure about high rpms because I lowered the rpms myself.
The noise first occurred at a high rpm under a load and stayed at low idle, load or no. But the noise isn't constant, I'll explain with the diagnostics.

As far as diagnostics I did the following: I let the engine cool down and sit over night, the next day I started it up and didn't hear anything. I brought the rpms up (no load) and still didn't hear anything. After a couple minutes of high Rpms the noise started again, real quiet for a split second then shot up to a loud fast tap tap tap. I lowered the rpms and the noise stayed in time with the engine and I looked around. It is only on one side (stbd) and almost sounds like a rocker arm needs adjusting.

Thats about it, if it were constant I would just believe it were a rocker arm adjustment or a push rod but this seems more like a lifter to me as it goes away. However, the first thing I will be pulling off is the rocker arm cover anyway but I still believe it to be a lifter. Besides, even if it were a rocker adjustment I would still be asking the same question : )

I hope this helps explain. I have done lifters before I just never really touch Ford engines, and on the rare occasion that I do they are mercs so that is why I'm a little hesitant. Thanks again for the help so far.

Re: Pleasurecraft lifter question

I don't really think you have lifter problem. I would start by carefully checking the firing order of your plug wires, then check the timing.

Re: Pleasurecraft lifter question

fords have a habit of pulling the rocker studs. If a valve sticks the stud can come up just enough to screw up the adjustment. If your taking the cover off put a straight edge across the studs. It's easy to fix.

Re: Pleasurecraft lifter question

As far as the firing order, the boat has been used plenty of times since the tune-up. But I did check to make sure the plug wires were going in the right place which they are. I didn't check timing though but will do that. I'll also check that rocker stud. Thanks again.

Here is a picture of the rockers. Lifters are all out, timing was fine.

Re: Pleasurecraft lifter question

Hey everyone, I found the manual and everything went back together nice and easily. I turned it over and it started right up. I'm having a problem now where oil is only going up a couple of the push rods (the rear ones). I let it run for a bit to make sure the oil had enough time to get where it needed to go but it didn't. I see in the manual there is a check you are supposed to do to check the gap and use different size push rods to get the right gap (between valve stem and rocker). I thought I was putting in a direct replacement lifter and didn't think this would be necessary to do. My question is would this cause oil to not go up the push rods like this? Thanks again for all the help so far.

Re: Pleasurecraft lifter question

Ok got it. There was a bunch of oil under all the fulcrum bolts and even though the bolts were torqued they weren't correct. When I got all the oil out from under the bolts it worked great. Thanks again.

Oil, will not hold the fulcrum bolts up.

Re: Pleasurecraft lifter question

I don't know then, but there was a lot of oil in the hole with the threads. That was the only thing I know of that I changed unless I did something else different. Either way though it is better. Strange.
