Has any one used this to seal a leak on a Ford 4.6 V-8 plastic intake manifold?

I've only used this in place of an exhaust manifold gasket (where it works just fine) so not sure how it'd work for an intake manifold. I assume you're going to just dab a little of this in the corners to augment a brand new intake manifold gasket. In that case I normally use ultra black. I wouldn't use any silicone in place of a gasket for a plastic intake because it will be very difficult to remove the intake manifold in the future without breaking it.

I would use this or some other sealant in a case where a replacement part is not available, but otherwise, you could probably pick up a used manifold at a salvage yard for under $50 and do the job the right way. I've learned that in the end, shortcuts rarely save any time or money.

If the leak is due to a bad gasket, this should work if carefully applied. I have used it on plastic and rubber with no problems. If the leak is due to a crack in the manifold, I can't be sure. But it's worth a shot since a tube of this stuff is cheaper and easier than buying and installing a new manifold.

I've been using this stuff for 20 years - I'd bet this would seal it. Works on just about anything. Just clean the surfaces up real good before application.

A plastic welding epoxy putty would work better if it is a crack in the plastic.You would want to roughen up and then clean the area first before you seal it over.

I've had a similar situation. As long as it does not leak, it will still work and is probably sealed well enough even though it is not all the way to the stop. You can use WD40 to lube the threads. That helps sometimes, but don't get it on the o-ring. This may be a sign your unit is needing replaced sooner than later.

I have in past. The key is to get the stuff in and start driving right away to spread the sealant inside the tire. I wanted to be sure to have enough pressure rather than not enough in a pinch. I can always reduce the pressure later. My tires go up to 42 so after a few minutes of conservative driving I check the pressure. I wouldn't try it on an already questionable tire, of course, such as a sidewall puncture. I've used this stuff on mower and wheel barrow tires also but I use the smaller size, in those cases, of course. I also have a mobile air pump that runs off my battery. Well worth it and if you have any worries about using the truck inflator version, you can always fall back on the air pump after using the smaller one, if necessary. Get a decent quality pump. It's great and they are relatively small too. Hope this helps.

i believe so as i had to only use 16 ozs.to do my 4 cyl.have drove over 4000 miles no leaks

I think that this Lucas product's application is specific to power steering systems, the fluids of which are generally power steering fluid or automatic transmission fluid. It seems to swell slightly the system's rubber seals, O-rings, etc. I wouldn't try it with an oil leak, of which I infer that you mean an engine oil leak.

NO it only seals gasket leaks, small block leaks, radiators, and other cooling system units. Product seals when exposed to air, combustion chamber etc. I have used Bars Leaks sealers for ove 50 years. Excellent results, NO engine damage.I used this product in my 2000 Volvo s40. it had cooling system and internal engine leaks due to over heating. Repair costestimates approaching $2,000. I added 1/2 can of this mid November 2013. Sealed within 30 minutes. small leak reocurredJanuary, resealed without further product addition. I was using a quart of coolant inside 100 miles. Use since adding Bars Leaks less than 8 ounces. None in last 5 months. Level today - full.Hope this helps.

Properly tightened with quality gasket should work. Check the mating surface of the valve for smoothness (where it tightens against the gasket). I have used 2 of these valves, and they are flawless. One of the suggestions was thoughtful but incorrect in application (please no offense to Cory. It is great that everyone tries to help). Teflon tape is only to be used on pipe or tapered threads and can only temporarily stop a leak in other applications (if you like, get back to me anytime for details).

I bet this would work. Personally I would glue or epoxy the leaky spot first though.

I used the seals that came with my intake system. Nothing extra was added. So far I have had no problem with any leaks. Intake works great. The engine feels like it has a little more power. I hope this information helps.

I had used this product on a 4.6l V8 Ford F150 (not the same yearas yours). I had my local mechanic put it in, he had not done or seen anything like it before, so I sent him a link to the video install and had him watch that. He could not guarentee his work, but he was amazed and it worked (saved a lot of money). still run today. I think it has been 4years. Good Luck

Yes, it's probably the cheapest and best alternative solution to finding out if your problem is minor or major. If your ML still leaks after properly using the Lucas stop leak you may want to have a mechanic look at it.

I am istalling it on a 48 Studebaker with positive ground. A word of caution. read somewhere if it installed in reverse polarity, the pump will run, but not output anything. And if your Ford is six volts, as my Stude, get a six volt pump. don't mess with voltage changes. Tipsfrom other owners tell me it will flow thru if turned off and only the old pump reunning. Guess its real purpose is to overcome vapor lock.Remember those ?

I have. I used to use this in my Mercedes diesels and it reduced the blowby significantly.

I doubt if it would harm the fittings material, for my purposes, it has always "just worked." Probably the smart move would be to test the sealant on a spare fitting first.

I repaired a wet washer fluid reservoir, and refilled the tank five minutes after the bond set, it has not leaked since. I believe it would cure and withstand relatively well. Also, the key portion of an ignition key/key fob combo broke off for my Ram. I glued the key insert back into the FOB and have used it to start the truck numerous times every day, so it withstands torque very well.

I haven't had any luck with it, but if you want try a bottle of Lucas fuel injection cleaner, that stuff works good.

No, it will leak out of the vent hole on the filler cap, and probably out of the plastic gauge. Be prepared to do some heavy lifting after it's filled. I use the front end loader on my tractor to get it off my truck. Al
