Whenever I get on the gas at like 3500rpm there comes a rattling sound from*I think* the drivers side row of rockers. I have not yet installed my 1.7 roller rockers so that might fix whatever it is, just wondering what it could be so I can fix it while I'm in there.

have you checked the engine oil level lately?
the noise could be any number of things... pull the valve cover and inspect everything.

Stock engine? Probably a valve floating issue :-P"Owning a 9-second Import is like coming out of the closet.... At first it may be surprising, but in the end, you're still gay!"

I personally think that a bunch of f***ing squirrels have stored 4 lbs. of small rocks and gravel in the valve covers. Happens here in Oregon all of the time.Comment

I have noticed what seems to be a bottom end rattle at startup on cold mornings, but it goes away when she warms up, but this is definately coming from the top end of the motor1989 Lincoln Town Car - "Anabelle" - Original block, .030 over with SpeedPro pistons, rods fitted with ARP hardware, FRPP +volume oil pump, GT-40 3bar heads, Crane 1.72 rockers, 89' Fox cam, 93' Cobra lower intake, Explorer upper and 65mm TB, 93' Lightning EGR spacer, K&N intake kit from a 4.0L Ranger, 19lb/hr injectors w/ 87 Mark VII ECM, cat/smog deletes, Big Brake conversion, 3.55 K-Code Trac-Lok/Disc brake rear axle, CVPI LCA's w/1" sway bar in rear, wagon front sway bar, BBK 2.5" off-road H-Pipe, Flowmaster super 40s, HPP wheels, 3G alternator w/LMR.com wiring kit, gear reduction starter conversion, Best 1/4 time: 16.0 @ 85mph.Comment

My 90's engine sounded like a can of marbles was being shaken under the hood once it warmed up. I was thinkin it was a dead lifter, but could only hear the noise through the stethescope when i stuck it under the back of the upper intake on the right hand side and got the tip of it on the intake manifold. You can use a broomstick to the same effect. start up your motor, have someone hold the rpm at the desired level, and go along the valve covers and see if the noise increases in any one spot along the entire length of the cover. You could also check your oil pressure with a gauge, but you gotta pull out your oil pressure switch and install the gauge. If oil pressure is low, could be the cause of your rattle. Could be many many things.sigpicVic Videos Here http://www.grandmarq.net/vb/showthre...676#post243676

Actually, I know what it is.
Piston slap. These cast-piston engines are notorious for it. It won't go away, unless you put new pistons in it. That, or the squirrels have put the black mark 7 on your engine.Comment

piston slap? what is that? I think it is a rocker arm that is not torqued down enough, and its hitting the valve cover.1989 Lincoln Town Car - "Anabelle" - Original block, .030 over with SpeedPro pistons, rods fitted with ARP hardware, FRPP +volume oil pump, GT-40 3bar heads, Crane 1.72 rockers, 89' Fox cam, 93' Cobra lower intake, Explorer upper and 65mm TB, 93' Lightning EGR spacer, K&N intake kit from a 4.0L Ranger, 19lb/hr injectors w/ 87 Mark VII ECM, cat/smog deletes, Big Brake conversion, 3.55 K-Code Trac-Lok/Disc brake rear axle, CVPI LCA's w/1" sway bar in rear, wagon front sway bar, BBK 2.5" off-road H-Pipe, Flowmaster super 40s, HPP wheels, 3G alternator w/LMR.com wiring kit, gear reduction starter conversion, Best 1/4 time: 16.0 @ 85mph.Comment

basically its the pistons flopping in the bores. The skirt smacks the cylinder bore and makes a noise. Usually it gets quieter when the motor warms up because the pistons expand a bit.86 Lincoln Town Car (Galactica).

well, I pulled off the valve cover and everything looked fine, I checked the torques on the rocker arm bolts and they were all to spec. I went ahead and installed the 1.7 RR on the drivers side. I have some questions about the explorer lower intake, as there is no hole for a sensor that is present on the towncar lower.
