ford explorer start up rattle. Better Oil?

Good Idea. I have done auto-rx in my BMW, Sort of ignored my wife's truck. Only 800 miles on this oil and filter so i think I will add RX and go from there.

BTW, she is only 1.5 miles from her office. This is hard on the motor in so many ways.

Good bicycle distance or even walking distance depending on how much time she has and whether she has to wear a dress or not. You are at a great distance for an electric car, then oil is a non-issue, other than the motor bearings, which likely would be sealed, no oil I am guessing.

Yeah, even MC filters can have startup noise, but as Gary Allan says, the "S" designation indicates silicon antidrainback and that is superior. May want to try.

Walking would be good. However she is 60 years old with walking issues, therefore handicap plates. I will try the "S" designation MC filter. Thanks

Hey ..60 is looking younger all the time..

 

[Rabbler]

60 is the new 30...
Or is it 0w20 is the new 20w50...I get so confused

Even though you have already had the timing chain tensioner recall performed, I suspect that you problem remains there. I remember well leading up to the recall that we had a lot of Explorers that continued to have the problem even after replacing the tensioners more than once. It seems like (although I'm not sure) tensioners used for the recall went through a few revisions even after the recall had launched. If it is still the tensioners, I have no good answer. I really think that Ford may not have truly found the root cause.

My best friend`s wife`s Escape (V6) always had bad start up noise. Her`s sounded like upper valve train rattle.

I don't think that Ford ever found the answer either. My Ranger has had the "TSB" done twice, and I still have a slight noise.

Where do I buy a MC filter with the "S" for my explorer? Dealer or are there other choices?

FL820S can be purchased at Walmart for $3.48

I think that's what fits your Explorer.

 

[Gary Allan]

Come on, Russell!! A lifetime has passed in BITOG minutes from the start of this thread. You should have had that new filter on long ago!

Have some charity ...we've got a pool going in the backroom to see who's right.

Well I ordered some Auto-Rx this evening. I will add it to my current fill which has only 800 miles on it and run it out to about 3,000 miles or so. Then use a MC filter and a good conventional oil for a rinse. Then evaluate the situation..

Its the timing chain rattling.

Every explorer with that 4.0SOHC I have seen has developed the problem, even after the owner has dumped huge money into replacing the tensioner or chain.

I have been stubbornly resisting OHC engines, for many years because of the rubber band drive, and then Ford has a better idea, but a 10-foot-long "bicycle chain" is not a better idea in my book. I guess the next vehicle I buy will have to be a restored model from the 80s or 90s. There was a brief sweet spot where EFI got pretty good, but pushrods and rear wheel drive were going out. The slight overlap makes for the best vehicles, early to mid 90s is about it.

This is not a "new" idea for Ford; they used it in the mid 1960's on the 427 SOHC; the engine with a 6ft long timing chain

 

[TallPaul]

Yes Ford did have that odd engine back then and in racing it was quite an engine. Not sure it ever was used in production cars to any great extent.

Also, remember Pontiac had an OHC inline six banger back in the 60s?

 

[Big Jim]

The Ford SOHC 427 did make it into a few production Mustangs. They were greatly detuned and not any faster than the other big engined Mustangs of the same era.

And I do remember the Pontiac OHC six cylinder. My girlfriend from the time owned one and I drove it from time to time. It ran really well for an in line six. That was the first production engine as I remember to use a timing belt.

The 427 SOHC was never officially fitted in ANY production Ford car...... FROM THE FACTORY. You may be thinking of the BOSS 429 Mustang, which was produced from 1969 through 1970 to facilitate the ability for Ford to run the engine in NASCAR. The version of this engine put in the Mustang was a pretty crippled version of the Can-AM engine, which weighed in at 494ci and made in excess of 800HP. There were a number of the 494 Can-Am engines fitted by TASCA into BOSS 429 Mustangs and were sold under the TASCA Super BOSS moniker.

It (the 427 SOHC) WAS however, available as an over-the-counter engine; available at ANY Ford part's counter. It carried a VERY hefty price tag (almost the price of the car!) but could be dealer-installed for somebody who ordered it. It was never available "detuned".

There were two variants of this engine:

The 1x4BBL and the 2x4BBL. The latter made 657HP at 7,200RPM. The most powerful production engine of the time.

Ford also produced a DOHC engine based on the 289/302 Windsor. It had an elaborate gear-drive setup instead of timing chains and was used in the Ford/Lotus Indy cars.

Overk1ll,

You are right. I was confused with the Boss 429.

The noise didn't go away,until I switched over to Amsoil ASL5w30.
Just my experience

Completely different motor. Yours is the pushrod engine, his is OHC. Yours would have been LIFTER tick; completely different.

My '96 was the same engine as yours. It's had M1 in it since 100,000Km. Has 296,000 on it right now (my sister owns it now) still on M1, still running strong.


Hydraulic lash/lifters adjusters are in principal the same whether they are down inside the engine riding on top of the cam or OHC,the only difference is the missing push rods and location within the engine block.The same issues with sticking,bleed down and face wear are true of both types.On 4.6 and 5.4 V8 engines the ADBV is critical because the filter is horizontal,on this engine it isn't.I would bet on the tensioner as the source of the noise which is common to all these motors,because they are fed by the oiling system they can get varnish in them and stick.ARX works wonders on these.
BTW for the poster who said the 427 was never used in a production ford.The Thunderbolt was a production car that used this engine.The Twisted Hemi 429 was used in Mustangs but a few did find their way into a small production of Cyclones.
