![Top 5 Symptoms of a BAD TIMING CHAIN [What to Look Out For]](/img/n.gif)
You guys really deserve more subscribers. Ive been watching your videos for a couple months and you guys really put a lot effort into them. Thank you for quality videos
Well...thanks! We might suck at Search Engine Optimization. LOL. We rely on folks like you to spread the word.
AutoRestoMod Muscle Car Resto and Modifications no problem! I've shown some friends your channel already and they enjoy it too. Keep up the good work.

If you need to replace the fuel pump (mechanical), while you have the pump off is a good time to check the chain, as Jeff said to rotate the crank backwards, you can feel the slack through the pump opening.
Right. BUT that only works on 1962 to 86 Ford stuff. Most other American V8s are not "gifted" with that ummm test port. =)
I have become a fan of this channel. Great information with very likable instructors. Thank you so much!
When you shut off the engine and go to restart it and it just makes a buzzz sound from the starter due to no compression then pow backfire.
Its time to then change that chain
I had a 351W that skipped a tooth or two. Did the wrench test you showed. Engine rotation direction and the button moved right away. When I checked the other direction, it took a full 90 degrees of turn to move that little dude. New chain and gears and runs like a top...mostly.
Lot of real good info love the father and son bond. Keep doin what you do. I guess my loose chain is no good....thanks
Super easy to pop off the fuel pump and reach in and touch the timing chain and check for tension
There are 2 top dead centers on a 4 stroke engine, probably important to say which one. Also, never heard of a rotor referred to as a "button". Interesting.
"probably definitely???" Clarity beyond all measure... :P
Goodson has a crank Turner socket to rotate the engine. Also engine tools. They have valve seal tools. OTC has tools.
Dang, now we'll have to spend even MORE money. LOL Thanks for the heads up.
AutoRestoMod Muscle Car Resto and Modifications The right tool gets the job done! They help you do jobs faster and easier. I have most of their valve seal tools. The valve seal pliers replace positive seals easy. The valve seal protector is shaped like a bullet and fits over the stem and protects the seal. There are crank sockets for Ford, G.M.,and Chrysler. Mac Tools and Autozone have a damper installer. A Ford 3.8 requires a OTC Ford damper installer adapter. Clothes-line in the cyl. can be used to lock the engine to remove and replace the crank bolt. I used a soda straw to feed the clothesline in the cyl. Use Permatex 14a on bolts that go into coolant passages. You can use washers to replace axle studs. To compensate for chain slack, lift up the distributor at #1 TDC on comp. stroke on 0 and point the rotor at #1 cap. Turn the distributor way back against normal rotation and lower the distributor. Turn the distributor for normal timing. Install everything and set the timing. You are compensating for slack. The crank has to turn less to fire #1. This translates into POWER! Watch it fly! You can also do that if the chain jumped to get it to start.
The front seal dosen't even touch the crankshaft. It rides on the harmonic balancer.
I'd love to know how far is too far. How much balancer movent is acceptable. (Before rotor shows movement)
.5 degree?
5 degrees?
Geat , I was waiting for that video ! :) Thanks Jeff :)
I have this problem also, I'm thinking the timing chain issue is causing to afterfire out the exhaust @ 5200 RPM WOT.
Might be.
@@AutoRestoMod Appreciate the reply, collecting some information what could be causing the issue.
Heck ya great show!!
I’m going to change out my timing chain on my 79 F150 302. Does the two piece fuel pump eccentric go bad or not? Furthermore I noticed after I took off the upper sprocket, the camshaft thrust washer had noticeable wear. Should that be changed too?
If wear is noticable, yes. If the fuel pump eccentric does not spin freely it too should be replaced.
Cam was right, you should have put a cam in it, but just a RV cam, you wouldn't have to change any thing else as they give you more bottom end torque, and its going into a ranchero.
Will a bad timing chain cause low compression an low vacuum
Low compression is typically an issue with rings or valve seats. low vacuum can be indicative of valve sealing or rings. If the car is smoking (blueish white smoke that does not dissipate) Then you most likely have a ring issue.
Thru Itall - It will cause low manifold vacuum. If compression is otherwise good (let's say maybe it's had a ring job in the past) the manifold vacuum will come back up only at higher initial ignition timing. To add to the issue because of manufacturing tolerances, even a fresh chain may still leave a camshaft with late or retarded timing. This is one reason savvy tuners always use a degree wheel. Even a stock grocery getter will benefit from a correct crank and cam relationship.
5:00 mark if your just looking for how to troubleshoot it
And 0:00 if you want to help me make more videos...
@@AutoRestoMod sorry I didn’t realize that would affect your view count.
...self-restraint? what's that? im already $1000 deep into my ranchero and im starring down the barrel of another $6k (eng, trans + axle)
If that engine is going in the ranchero why not do the top end stuff?
Sorry to be unclear, the Summit Racing 5.0 will be eventually headed for the Ranchero. Some lucky soul may end up with the 260 from the hard top.
Is a 1974 pontiac bonneville 400 engine a interference engine or none interference engine???
If the chain is bad and breaks, it can damage valves.
@@AutoRestoMod thank you..I have a no fuel no start problem..I'm not getting any fuel pressure from my tank..or when I put gas in the carburetor and still no start...it cranks but no start or fuel..I checked lines and all no fuel coming from tank at all..i have new fuelp pump..new plugs,wires..any ideas?? Please..any help is very needed it was my daily driver
still have the 260? want to donate to a '62 Fairlane restore for a first timer? i live in Augusta but will be moving Johnston a little later this year. love you vids! thanks!
Not sure, but when you see the 5.0 HO going in drop us a line!
when 13deg.is way past #1 on distrib
LOL
That timing chain is like a fart in the breeze, throwing a hotdog down a hallway
Enough of the advertisement wish it would just get to the issue
Richard, this is how I make my living. Ads are a beneficiary and valuable part of me making these videos. Content creation is a hard job, and I do my best to keep the ads as unobtrusive as possible. BUT, I won't work for free. Would you? You know, go into work on Monday and say he boss, I'm good a good hearted guy and I will do this job for nothing. Don't think so. I can't do that either. I spend at LEAST 40 hours a week on video production. I should get something for my time.
@@AutoRestoMod sorry if I offended you but do what you have to do
damn look at her
