A little defensive for sure but said they get 1 call a week during track season for this issue.
My R300 kit was supplied with an oil cooler, I wondered if Seb's R400 was supplied with a bigger cooler.
Your Cosworth engine has updated big end shells, I suppose they may be more heat tolerant, but everyone tells me oil selection is critical. I'm switching to Millers 10W-60. What do you use? I'm certainly still very nervous now!!
