VVT Oil Feed
2 Attachment(s)
Hi guys,
I've just joined the forum. I've got a 2002 Sport that I'm turbocharging. I've got a Reverant built MS3 installed and my turbo should be arriving today so I've decided to tackle the oil supply. As I have the VVT it seems sensible to take a feed off the VVT 'unit?' on the cam cover. I believe this has been done before but I'm having trouble finding any information on it. Does anyone know if I can simply take out the bolt 'A' and make a fitting or if I would need to drill and tap somewhere like 'B' in the photo? Any advice on how I should go about this and whether it's a good or bad idea would be great. Cheers James https://www.miataturbo.net/attachmen...ine=1462361210 [img]blob:https%3A//mail.google.com/4abefaef-ee21-4c2b-a6c9-7aa1ef663ba7[/img] |
Tee off the oil pressure sender under the intake manifold like everyone else. Buy the TSE adapter and then run your -4an line around the back of the engine.

I've taken the oil supply from the VVT actuator. The link you posted above doesn't work, so I don't know if it is A or B. I had a custom fitting made at a machine shop for the oil line.
|
any concern on feeding a journal bearing turbo from the VVT location?
|
What concern?

I'm using A with a ball bearing Garrett turbo. No issues so far.
|
fuck it then. I'll just feed my TD05 from port A in the pic.
Is that 1/8BSPT? |

Oh my god. Never thought to use that location. that would def simplify plumbing under the manifold and would be far easier to reach to correct any leaks than on either side of the block.
|
I've been reading soviet's build thread over the last few and I know they talked about it somewhere around page 50-60. From the way it sounded it's definitely a decent option.
|
I'm not sure what the threads are for that port, but its close to 1/8 npt. I ran a 1/8 npt tap through it and its working great for me. npt to AN fitting are very easy to find :)

I got the car running yesterday and I've been trying to track down a nasty noise. I've narrowed it down to what seems to be the VVT mechanism, it sounds identical to this..
I'm wandering if I'm pulling too much oil away from the VVT mechanism but this seems unlikely to me as I'm running a 1mm restrictor. Has anyone who used this location come across a similar issue? If not I'm thinking I have a more severe issue as it does sound pretty bad. Oh and I've measued the plug I took out, it's outer threads measure 9.81mm if that's any use. https://cimg3.ibsrv.net/gimg/www.mia...c6be4d1c98.jpg Oil feed plug |
Replug the hole and see if it goes away?

Thanks for the reply, I didn't fancy removing the turbo again (as the turbo wouldn't have oil) with my DIY manifold it's a pain to remove so I've ordered a cheap ebay sandwich plate to try a different feed, seems like the NC cars suffer from a similar noise but I'm not sure how similar their VVT system is to the MK2.5's. I only drove the car a few times before starting the project as I have another MK2 that I use normally and didn't really rev the engine with the bonnet up so I'm wandering if it's been like it all the time and I just haven't noticed. I'll update this if I make any progress.

Also if feeding the turbo from a sandwich plate, that's all pre-filtered oil.
You can move your pressure sender to the sandwich plate, and source the feed from the 1/8" bspt sender port. |

Sandwich plates work, but cheap ones have always leaked for me. Return it and buy that tee fitting and a length of -4an line to go off the oil pressure sender. For diagnosis obviously.

Does Savingtons/TSE's oil and water line kit use this port?
Edit: Nvm, im stupid. Carry on. |
I'm trying to order the oil and water lines and fittings for my turbo build and would really like to use location 'A' for the oil feed. Did anyone figure out what kind of adapter is correct?
|
Wow.
OP Installs oil feed from Port A, soon gets strange noise from VVT assembly, wonders why.. THEN people reply wanting info and parts to also use port A.. To top it all off, the thread is only 2 pages long, surely we all didn't miss something here?? I would run the oil feed from the oil pressure sensor port like everyone else, on any car, for decades has. If it aint broken, don't fix it ;) |

I've been using location A for a year now with now issues.

FWIW the sensor port and the VVT are the same block port, one is just closer to the VVT assembly.
