Replacing Hydraulic Lifters

is this in Africa TAppets ,are you sure it has this< and is HLA?
what engine is there exactly?, (step 1 to work any engine is. this.
gas/petrol of diesel? engine size. like, 3.0L? V6?
wiki
The 1400 Bakkie was assembled by Nissan in Rosslyn, South Africa (Nissan)

1.4L engine a very small pickup truck and tiny obscure engine
that wiki fails to identify.
buy the manual for NISSAN.
it is not a diesel ,and this list is all 1.4L listed by maker,1.4L and in year range.
GA14DE DOHC, 2 CAMS? AND ROCKERS? 12VVALVES
The GA14DE does not have hydraulic lifters, so special shims are used to adjust the valve clearance.

CGA3DE DOHC, 1,4K Sold as but is 1.348L
data super hard to source on the engine.
one photo shows head cams over valve stems, no tappets at all
see photo, I see bucket lifter there, so are shims.

CR14DE, with vvt

The Nissan CR14DE motor does not have hydraulic lifters, so special valve lifters are used to adjust the valve clearance.

so knowing this engine fact and the exact one makes this more easy

lacking manual or engine name, i'd look first.

CDA3DE, FOR SALE, SEE THE BUCKETS , I DO.

Hi. I can give you a simple, but time consuming test to do to check your intermittent compression problem. New hydraulic lifters cause a lot of problems until its settled. Remove the camshafts and the hydraulic lifters. Take each hydraulic lifter and put it in a vice(becarefull not to damage them) and squeeze out all the oil in the lifters. Then put them back and replace camshaft and allign timing marks. Check compression ratio. What happens sometimes is that the oil pressure is too high(stuck oil pressure release valve or cold thick oil) and this causes the oil pressure to put so much pressure on the hydraulic lifters, that it slightly forces the valve open. That will cause your low compression as well as backfire through the intake.

The VG30E engine has hydraulic valve lifters so there is no adjustment possible. You can try replacing the oil and filter, substituting one quart of ATF for one quart of oil. Let it go for 3,000 miles and do it again if necessary. If after the third time the tapping is still there, you will need to replace the hydraulic lifters.

What engine do you have (size)? Valve adjustment is generally a thing of the past after the introduction of hydraulic lifters (no adjustment). In 1994 your engine should have hydraulic lifters and are not adjustable. Is this a high performance engine? New camshaft, lifter, and rocker set that are adjustable?

hi, on your vehicle the valves are not adjustable after about 1990 they started using hydraulic lifters, so if you have top end engine rattle then the chances are these lifters will need replacing or worse case the cam lobes could be worn if this is the case then your going to need to do a top end rebuild.

to replace the hydraulic lifters your going to need to remove the cams so as you can get to the lifters under neath the cup they sit under so its quite a big job.

the older type valves were a lot easier as you could adjust them with screwdriver and measuring guages but they started using the new ones as they made less noise and lasted longer, but the downside to this was that you need to do more work to replace the lifters.

let me know how you get on or if you need further assistance ok

As far as I know all hydraulic lifters can go bad, collapes or stick. And yours are definately hydraulic lifters, rollered yes, which will make them more durable, but they can go bad. The machine shop should have down a leak-down test on the lifters. That is the only way to determine if the lifters are good. I would check that you have proper oil pressure, I'm sure you do. I bought a "rebuilt head" for a Saturn DOHC engine, and the machine shop never did a leak down test on the lifters, and I had the samething happening.

The lash adjusters are hydraulic and will have to be replaced. They can be replaced without removing the head, you just have to remove the necessry intake & parts that restrict your access to removing the valve covers, then remove the rockers (that's where the adjusters are of course), replace the adjusters and reassemble. Make sure you note the direction of everything, once reassembled it should fit exactly as it did before, with a little less slack.

All engine parts like this need oil. Soak the valve lash adjusters in oil overnight before installing, preferably in a warm location, or place a warm light next to the container you put them in, they work like valve lifters, just smaller.

Good luck

Please don't forget to rate!!!!

2.2L Engine When installing new lifters, a pre-lube should always be applied to the lifter body. It is also a good idea to prime hydraulic lifters by submerging them in clean engine oil and depressing the plunger using an old pushrod. This allows the internal components of the hydraulic lifter to coat with oil before initial operation in the engine. All lifters should be replaced when a new camshaft is installed.
If any valve train components (lifters, pushrods, rocker arms) are to be reused, they must be tagged or arranged during removal to assure installation in their original locations.

1. Remove the rocker arm cover.
   
2. Remove the cylinder head assembly from the engine.
   
3. Remove the bolts retaining the lifter anti-rotation brackets, then remove the brackets.
   
4. Remove the hydraulic roller lifters from the bores.
   
5. Inspect the lifter and lifter bore for wear and scuffing. Examine the roller for freedom of movement and/or flat spots on the roller surface.
   

Remove the bolts retaining the lifter anti-rotation brackets ...



... then remove the anti-rotation brackets



The lifters are located in bores in the engine block



Use a lifter removal tool to remove the lifters from the bore

To install:
If installing a new lifter, coat the lifter body with a suitable camshaft pre-lube

1. Install each hydraulic lifter to its bore being careful to align the flat sides (top) of the lifters with the flat sides of the anti-rotation brackets. When properly installed the flat sides of each lifter are aligned parallel to the anti-rotation bracket. The roller at the bottom of the lifter is parallel to the camshaft lobe.
   

Make sure to properly align and install each lifter as improper installation of the lifters or brackets could result in engine damage.

1. Install the anti-rotation bracket retaining bolts and tighten to 97 inch lbs. (11 Nm).
   
2. Install the cylinder head.
   
3. Install the rocker arm cover.
   

Removing the hydraulic roller lifter from the 2.2L engine

Yes, you've overtightened the lifters causing the valves to not close completely. If you did not prime the new lifters before you installed them and tightened them with the engine off they are most likely collapsed. back off all of the rockers to just snug and make sure the engine is running when you readjust them. Usually you need to let new lifters sit in a can of oil for a while to fill up. I've used a syringe to fill lifters prior to installation. Did you replace the push-rods also? If so were they the same length as the originals?

there is no tappet settings, they have hydraulic lifters.
if tapping its because of lack of oil changes.
the lifters are coked up and no oil fetting in.
try engine flush and new oil with hydraulic lifter additive.
if not a set of lifters.
i have got a complete head i can knick the lifters out of for £40 and the set is yours.
