Ok well i kinda gotta problem and im asking for some help. My 89 ka24e has a problem, there is a tapping sound coming from my engine at first i thought it was there wasnt any oil and when i checked there wasnt so i added some and still it taps. I really wanna say its the valves but im not super sure can u adjust valves or is it hydraulic? has anyone had this problem or knws how i can fix it thank you all.

 

this is very common but no you cant's adjust the lifters. you have a few options though.

1. get new oem or adjustable adjustable lifters.

2. switch to a full synthetic oil. if you are currently using a full synthetic then this is not an option any more.

3. pour some seafoam into the crankcase before your next oil change and hope that works. there are other additives out there for noisy lifters but none that i've tried work as well as seafoam.

4. take the lifters off, disassemble, clean, and reassemble. easier said than done.

with the exception of buying new lifters i've tried all theses and the seafoam is easiest and least expensive so i'd start there.

 

what do you mean get new adjustable ones? how much will that run
and im using normal 10w 30 oil

switching over to a full synthetic could help but i'd try seafoam first.

 

damn hella money im lookin for a cheap fix so ill try the 7 doller seafoam thanks alot for the site

 

iirc the ones at the dealership are like $25 each.

 

o really so i can change just a couple of the rocker arms and lifters?

 

I would say since there was no oil in the motor, it is most likely rod bearings, which would make it a cheap fix unless you spun a bearing.

 

SEAFOAM SEAFOAM SEAFOAM!!! I swear by it. Completely stopped ticking lifters in two out of the three cars I've owned. (and the third car never had ticking lifters.)

 

Castrol GTX 10W-40!!!

 

idk vinnie if anything i'd suggest a lighter not heavier oil. but that's because imo the problem is a stuck lifter(s) and not that the lifters aren't retaining the oil. if the lifters are not retaining oil then the seafoam won't do much because it will thin out the oil more. but i'm just thinking out laud here.

 

There are more moving parts in a SOHC valve train than a DOHC. This will tend to cause more friction on the moving parts such as the lifters. Friction causes heat. Higher weight handles higher temperature better than lower weight oils do (obviously).
Heavier oil will also tend to sit in the head longer than a lower weight oil that will tend to flow down to the pan sooner. This means a heavier weight on start up will tend to protect the valve train as it can retain alot of the oil around retainers, and the lifters. I would say between 24hour start ups. This will do less damage then probably a lighter weight oil would do. Since both a 10w-30 and 10w-40 use 10w polymers it will flow almost the same almost having the same viscosity during start up.
What would be better is using a 0w-50 like mobil 1, or NEO synthetics but then that just starts to become expensive, and with old seals will probably just drain all over the place.
