Hi everyone and to those of you who look at this post thanks in advance! My 01 ls 3.9 has had the timing issue fixed but i am getting a clatter from the front or middle of the engine it is a really hard sound to compare or explain its like a clatter and it gets louder when in gear! My brother who is my mechanic tells me it has something to do with the variable timing but can not find any info on it? I am also having a problem where it will not start right away and in order to get it to start i have to push the gas pedal to the floor for a second or two until it starts after it starts the exhaust is really gassy smelling but sometimes it starts right up like it should? It does not make any difference if its cold or warm kinda like rolling the dice every time:((( Any help would be greatly appreciated!
 
The '01 LS didn't have VVT. I would get a new mechanic...
 
First, you should probably get another mechanic. Do you have any other brothers? Your 01 LS does not have variable valve timing.
Your sound description is not good enough to diagnose that problem from here. There are several possibilities for it.
Your hard starting problem is probably your IAC. They get old and dirty and start to stick closed. It would probably be best to replace it. They aren't expensive. Alternately, it could be one or more leaky fuel injectors.
 
lol nah i am gonna stick with my brother everyone can be wrong! He seemed to be able replace all the timing guts and make it run again so he knows something but i sure will like to be able to tell him there is no such thing on my car! I had never even heard of such a thing before he said something about it? IAC sorry i have to ask but what is that i am kinda car stupid? Oops idle air control valve found it! My brother had told me it might be a injector losing pressure to not sure how a person would go about finding out which one or ones are doing it? To maybe describe the sound better it would be a cross between a clattering valve and a bad pulley! it is not constant and it gets louder and when in gear?
 
Pull them [fuel injectors] all out still attached to the rail and see which one(s) is/are dripping. Easier would be to listen to them with a mechanic's stethoscope.
I'd try changing out the IAC first. It's easier cheaper and even if not the problem you will need to change it sooner or later anyway.

There is a such thing as variable valve timing and the Gen II LS has it, however your gen I does not. If he's replaced the timing tensioners and chains, I don't see how he could not see that the VVT parts weren't there.
 
so wait, he has replaced all of the timing parts and he still thinks it has variable valve timing?
 
Lol idk like i said i never heard of such a thing before today! Any idea on a price of the iac? I kinda browsed and seeing $110?
 
lmao nope i fix computers not cars i have always had my brother around to take care of that part! Anyone but me! I am not mechanically inclined i can take it apart but for some reason get confused putting it back together but only when it comes to mechanics? I can take a computer apart and put it back together just fine but when it comes to cars i am lost....:confused: But seeing i have gotten 34000 after the timing fiasco I am gonna go with my brother even though not as smart as he makes out to be is a ok mechanic btw he is a maintenance guy by trade fixing cars is only a side job for him! i am gonna relish the fact that i will be able to tell him he is wrong tho lol!
 
Hello sorry to bother you guys again with stupid questions but i have some more details i wasn't aware of my brother says on the front of the bottom of the engine under the harmonic balancer is a black pan and it is not the oil pan that is where the noise i have is coming from he told me he will not take it apart to find out what is under it until he can find out for sure what is under that pan all the schematics he has does not reference any thing about it? Any help would be greatly appreciated? Thanks in advance!
 
Under the engine, just behind the damper (aka harmonic balancer) pulley is the black oil pan. There isn't anything else down there that I would call a "black pan." He may be thinking that it is not the oil pan because he is used to them being longer (front to back) than they are wide (side to side). A good clue would be if he sees the oil drain plug on it.

So, you are saying that he didn't really "replace all the timing guts." Replacing the primary chains would have required the front of the engine to be disassembled.
 
oh lord, how many clues do you need before you figure out that you need a technician with at least a fair amount of experience with these cars.


I'm not trying to say your brother is a terrible mechanic, I sure he can work magic with a chevy 350, but this motor requires a little more of a delicate touch...
 
ok not sure if this is even what he is talking about its dark no jack or garage took some random pics not even sure myself what i took pictures of besides the new ac pump i just had replaced? I know he replaced all of the timing chains and tensioners without disassembly of the lower half of the engine meaning oil pan off but then i am not sure of anything technical but i also know i did see the front of my motor off and the alternator water pump tensioners and chains all replaced then put back together so i would say yes all of it was replaced?

Not sure if i need a clue he did this as a favor for me normally he does not get this in depth with vehicles but in the process it prepared him for fixing his supercharged cobra which apparently used the same plastic tensioners which have since died on him and is in need of fixing but after my car he is putting it off cause it is a huge expensive job!

That's a picture of the oil pan. I think that this is going to be a case of using a cheap mechanic costing you a lot of money. If the noise is from the oil pan, the timing chains are messed up or worse.

You have some leaks that need to be addressed there too.
 
Ok i am the mecanic that you pros say dont know crap. I asked my brow to ask a simple question. What is under the black cover? Since he is using the car and lives 30 miles i cant take the cover off and see right now. Call me stupid or dumb but the thing that looks like an oil pan has a drain plug in it. The black cover does not have a plug in it. As for the Chevy 350 comment. Not. Try supercharged 1997 cobra DOHC. not a baby brother 4.0 or 3.9 since lincoln cant decide what to call it. Usually a picture would work. Funny thing is the motor in my brothers car is identical to the 2005 lincoln ls i work on.
 
I think i talked my brother into registering and posting here i think i am out of my depth here he tries to explain it to me but of course i dont understand maybe he will be able to post here and explain! I joined this site becuase it was shade tree mechanic friendly and if it wasnt for this site my timing chains would never have gotten fixed at all i see the leaks ik the valve cover leaks and the only fix is to replace them and its kinda a job just to get the valve covers off and i just dont have the cash to stick into it right now:(
 
Yes i had the front cover off. How do you think i changed the junk plastic chain guides. Cut the chains and put master links in them like the bs kits i see on ebay? You can put that crap on your car. Yes I know some crap unlike everyone is assuming. I have worked on a lot of DOHC engines because the shops are smart enough to ship em out the door. Who wants to do an 18 book hour timing chain job! Also I made my own tools for the job from a picture from ebay. On company time at $30 an hour! Or is that to impossible,
 
Once again the only thing i noticed between the 01 and 05 is they ditched the stupid hydraulic fan and went to an electric. I didnt have both cars there at the same time and take them apart at the same time. So no answer on whats underneath the cover?

Well..... The '03-'06 has VVT and the '00-'02 doesn't. That is a major change.

As Joe said, oil pan......

well since there are differences between the 4.0 and the 3.9, they call them what they are, lincoln is not confused here

statements like this prove to us that you dont quite know as much as you think you do...
 
On the attatched image that is what i was looking for. Thank you very much. To the lower left of the crank is a thing i confused for a veriable timing actuator. What is it? There i an intermittent noise coming from under that cover that sounds like its right on the other side of it. Been there as long as my bro owned the car. Timming chains didnt fix that noise.
 
I changed the chain guides and tensioners also. + i changed the waterpump, tensioner, rebuilt the alternator, and lastly the air con pump bearing crapped out and was replaced. I need to know what could make noise like a rattle but not chain slap, rod knock, intermittent under there. Feels almost like its vibrating the cover hitting a solid piece of casting. And yes the cover was smacked and i will probably have a hard time re installing it and getting it to seal. This is why i am asking instead of just taking it apart.
 
Yeah probably ran without blinker fluid too long which fried the muffler bearings. You should probably just swap in a LS1.
