Oil Starvation Discussion

[Benckj]

Don't you have a megasquirt? Can't they do logging? If not you could tack on $100 with of Arduino bits and make something that works. Aren't you an engineer of some type?

Yes I have a Megasquirt, can datalog but lack an oil pressure sensor and track to play on. Like you I don't believe I have an oil starvation issue due to better gen 3 sump, pump and return lines.

This thread was purely to discuss issues and failures with other owners to try and determine common failure modes with the aim of prevention. Granted it's only empirical ingormation provided by those who have had or avoided a failure.

Can I just state the obvious? Don't do motorsport in a car not designed for it. Be proactive about preventing problems, instead of reacting to it once it's happened. The modification list varies with what application you are using the car in though.

Accusump
Gated and resized sump
Or dry sump
Those are the options
By the time your oil light is on .. it's over , you won't be abike to react fast enough to save it .
As for oil type etc ... it's a red hearing

Look at the 2kcup MR2s.
Gen2 engines were going bang like anything,
Don't believe there has been a single Gen3 failure all season (just finished).

[Benckj]

That's a good indicator that gen3 oil delivery is superior to older design. How many gen3 engines participated in 2k cup?

[thelinuxwarrior]

5x Gen3 MR2s I believe.
There we some gen 3 celicas also, but don't have a count etc.

[Benckj]

That is more than I would have expected. So if we consider everything being equal between the MR2's what are the improvements over engine components which make the NA gen 3's better than gen 2's?

[JasonFriday13]

This sounds more like a project management meeting than a discussion.

The main difference I think is the sump design. The pump itself is the same on all SW20's, it's just the housing is different due to oil filter location. Surely someone has already discussed this before, why are we doing it again?

[Benckj]

Yes, sump and filter location is different but also.........
Gen3's run a larger flowing oil pump but may be only the larger sprocket that is different?
Don't the gen 3's have a different head with larger cooling & oil ports?
Any other contributing factors?

BTW we are doing this again as we keep destroying engines. Either we are not changing what is required or we don't understand the problem.

[EssDub]

Or, owners are just driving/maintaining the cars like retards and letting the oil run low, while trying to improve their individual 'Takumi' driving techniques.

Willful ignorance is a dangerous thing, especially if those who are grenading their motors read any kind of decent forums on the issues.

[JasonFriday13]

Alright then, I'm just not going to participate any further. I've stated my opinion, and from here on I think this is just raising awareness about it.

Baffle the sump. Cant recommend this highly enough. At least on the 4AGE, the oil pickup is surrounded by a plate with the intent to keep oil in the right spot, but its not enough. I would weld up the holes in order to create a barrier for oil, so it stays near the pickup.




I would also at the minimum install these: https://twosrus.com/catalog/product_inf ... cts_id=889

Cameron have you put the baffle kit on? Was did you see any value in it?
I have to sort my sump so I can fit my 4agzte. Welding up the holes in the existing baffle sounds like a start and the Acusump is a good move if you want to spend the money but my car is costing way too much now and I have a OTT hilux to finish too so DIY sump mods would be good
