Pardon the dumb question, does an overhead cam engine have lifters? I know there is the cams, followers, springs and valves but I dont know if there are lifters. The reason I ask is because my Cobra seems to have lifter noise when on a cold start. The sound goes away after 20-30 sec. and is sometimes faintly heard when coasting. Anybody have any ideas?
Do DOHC have lifters?
- Thread starter LaserSVT
- Start date
I assume you are talking oil filter
The oil and air filter are Ford OEM.Why, whats wrong with Fram's?
The previous owner said it made the same noise with him a couple times on really cold mornings, forgot to mention it to me before I bought it. For me it makes it every morning, I dont want to hurt the engine but cant afford a valve job and its my only car.

not OT
i was going to post the same thing
alot of Fram oil filters (unless they've changed them) don't have anti-drainback valves so all the oil drains out of them when you turn off the car, hence the ticking on startup
since it's OEM make sure it the right one, FL-820 S

lifter, tappet or hyd lash adjuster, either term(s) is/are correct and yes, your DOHC has 32 of them and if abused, like over revving, they can weaken and cause a tapping noise. what weight oil are you using?
Exactly. It's not off-topic. I used to own a lincoln Mark 8 which also had the 4.6L DOHC in it.
WHen i ran a fram filter on it, it would cause the chain followers to rattle so badly on startup.
When i changed to an OEM filter, the noise stopped. Frams just have poor anti-drainback properties

Thank you! I just bought the car and have put 1k on it in the past week and a half. It had an oil change the day before I bought it and was just regular 10W30 and a Ford oem oil filter, FL-280S I think
So tomorrow I am going to change the oil, figured I would get some cheep oil and two filters, do a change and run it for a few min, then change again. Dont know if this is needed, but have heard to do it from several people to try it. So what kind and weight oil should I use for this hot Texas weather. Also what kind of filter should I get? K&N, Ford, NAPA gold? I know NOT to get a Fram. Thanks, I was wondering about that
Its the thought that counts

DO NOT USE 10W30 in a DOHC Cobra motor!!! You need to use 5w30 and I would recommend a Mobil 1 filter and 5w30 synthetic. The tick is normal unfortunately in our DOHC motors. The 7 and 8 cylinders have trouble cooling and they just start doing that from the heat.
If you run 10W30 in your DOHC Cobra motor, you will regret it. Tolerences are too tight. Please refer to your owners manual.
Good luck.
I wish I had the Cobra manual
I bought Quaker sae 30 and a NAPA filter, changed the oil, ran for 6 min and changed agaian with Mobil1 Synthetic 5W30 and a Ford filter. I dont get the tapping knock when warm, only when cold on first start. With the oil change I dont hear anything anymore Isnt there a fix for the 7 and 8 cylinder heating problem? Seems I remember seeing a crossover tube that was made to go back there

Personally, I don't think it makes a hill of beans whether you use 10w30 or 5w30. The 5-30 from ford was all about CAFE, not about engine lubrication. 5w30 is a bit thinner, and a bit easier to pump, slightly increasing the fuel economy. The tolerances in the 4.6 are not _that_ tight. In fact, they are looser than normal for longevity...
Ford even uses 5w20 in some cars, something I would immediately drain and replace if I bought one.
