very pset atm, it seems that my lifters are getting flat spots they are very noisy!!! My car doesnt even have 100k on it yet! Has any one ever had worn out lifters on their 34? If so what is the most inexpensive path to take? Also my coil packs are gone and now my clutch is going!!!!!

oil level looks fine, i have started getting the problem after i put in an oil cooler?? Could the oil cooler take away too much oil and starve the head of oil?

make sure the lines are round the right way (correct oil flow). In all my years i have never had issue with worn lifters in R34, but i see the cooler installed wrong all the time.

the centre hole with thread is return the outside hole is output.

went and sought some advice from a trusted and experienced skyline specialist in melbourne they are doumbfounded as well by the noise it is making....BUT they did notice quite a strong dint in the oil sump. They are thinking that the knock may have been hard enough to damage the sender = lack of oil to head, this is backed up by the fack my motul 300v has bubbles in it, any thoughts people?? im getting real nervous

Sounds like you got some issues mate. Frothing of oil is exremely bad.

Was the dent in the sump before the cooler went on? If so, why the problems now?

General rule of thumb is if you change something and then a problem occurs, look to what you just changed

maybe cracked oil pickup. Hard to tell without having the car to do some tests. Did the shop think the dent was big enough to contact the pickup? if so drop the sump asap and at least check it over..

performance shop i went to are under the impression that the sump can not be removed easily, need to take out the engine? big dollars for that

its not hard. Drop the front crossmember. the engine just needs to be supported from above with something like a engine brace. We have done in chassis rebuilds this way. In and out in half a day.

In fact we did wheezys (sau nic) car this way.

use one of these to support engine.

something new.....when i first start the car there is NO TICKING. it takes some slight throttle for the ticking to start?? WTF IS HAPPENING??

First of all you need to STOP running the car for starters, because you’re probably causing irreversible damage by continuing to run/drive it. Find the source of the issue, don't muck around when it comes to oil pressure problems.

Then drop the sump and find out what's happening with the pick-up. If the sump had a dint before, and all you have done is installed the cooler, then is sounds like you haven't added additional oil to accommodate the cooler. I personally would be checking the pick-up anyway just to be safe.

You can't just wack the cooler on, it will simply pump oil into the cooler/lines and the sump will end up with nothing in it, or very low, hence the ticking progression with throttle.

hi james , thanks for that info but cooler has been installed by a very trusted mechanic, specialises in track cars so im hoping he considered this. Also my oil level is fine and oil pressure in the block is fine so i dont think it would be due to lack of oil which still does not explain the bubbles in the oil. But i agree the less driven the better and im taking it in tommorow to attach a pressure gauge to the head and check oil pressure in the head, if that is low then we will check oil pickup.

I am unsure who you have been talking to but I don't know how you are going to do a 'pressure' test on the cylinder head when it is splash lubricated.

I hope you are going to be getting it towed to the workshop also. Any driving will possibly ruin it.

The frothing of the oil is usually caused when the oil lines are arse about.

You want to make sure you ask the workshop very specific questions if the engine is cactus. If they have fitted it incorrectly then they are liable for any damages. If they did fit it correctly then there has to be another reason.

If they are still unsure of what the noise is and everything is fitted correctly, then take a GOOD video of the noise and post it. I should be able to tell you what it is.

Also, if the ticking noise comes only once revved, then it's most likely not going to be lifters

We just finished rebuilding a rb26 for an SAU member... a reputable workshop fitted the oil filter relocator lines ass about...... every shop can make mistakes dont take anything for granted best bet is to check the line routing.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      The cam I am actually putting in (a few posts up) is actually smaller than my current one. At least duration/overlap wise. All the chop stuff I hear just sounds like an engine running badly, because it is. I then envision driving it around in 1st gear and being massively sad about it bucking to the beat of said chop. There is an idle video of someone with a similar cam floating around the internet, but mine is a custom cam (so is his) so it'll never be the same, plus the fact exhausts are entirely different. What I want to do is put some bullet mufflers/race mufflers in to replace a couple sections straight pipes that currently replace the two extra cats that I don't need. But this is even further down the line!

      I can tell you now, when the bracket that the little hydraulic ram attaches to snaps, with a subframe, and V8 from an AMG C63 on it, it sounds like someone letting shotgun off right beside you. It leaves your ears ringing, and a huge thankfulness that you never ever put a body part under something heavy that's only supported by a hydraulic lift...

      Water leaking into the rear trunk

      By Neostead2000 · Posted

      Still not a guarantee fix. I used a high quality butyl-mastiq (the black goo that's not really silicone nor polyurethane, same stuff they use from the factory that just spreads out like melty cheese), and I still get lots of water on both sides of the trunk when raining or washing the car. I also suspect the factory spoiler rubber gasket might not be sealing well, so I'm thinking of adding a thin layer of grey silicone around the bolt holes on both sides and see if that's where it also leaks from. The biggest issue is that these cars don't come with a drain hole on each side like other coupes and hatchbacks.

      Would seem to me to be appropriate to go GTR style bar. There are options with and without N1 vent holes, with the GTR lower lip integral (because FG copy). https://justjap.com/search?q=r32 bumper
