Yes, comes off the inlet. Has been fine until recently.

Need help guys. Don't seem to have any vacuum. Just reads zero on the gauge. Haven't tried boosting it. Hotpipe on turbo isn't getting hot either. Any ideas? Could it be a vac leak (no whistling noises though) or a sensor? This issue is not always apparent. Sometimes OK, other times not.

Surely thinner oil would run hotter?

Must mean Shell Helix H7 semi synthetic 10w40 is not good oil then? I'll keep my eye on it,see how it goes.

Depends what temperature it should be running at? I've had over 100degs oil temp after a steady motorway run. Isn't that a bit high?

What size oil cooler is recommended for these motors? Not used on track or abused in any way, and purely a summer car. Thanks

Need the following shims ASAP. What you got? 1x 2.70 1x 2.80 1x 2.85 1x 2.75 2x 2.90

Sorry, written badly. Just wondering if arp bolts have the brand stamped on the heads. And wasn't sure if they were internal or external drives.

Did a quick search, but couldn't find anything on this. Are ARP head bolts different size tool than stock? Are there any markings to determine if they are indeed genuine? Anyone ever reused a stock set of bolts? I believe they're torque to yield, so have to be replaced?

Literally just had mine rr-skimmed and valve seats done. Lol. Out of interest though, How much are you looking for?

I was looking at Victor Reinz ones as they are half the price as Toyota. But didn't know if they were any good.

Looking for recommendations for replacement stem seals, or are Toyota ones still the best? Prices vary massively online, from £15 a set to £60 (Toyota)! I know you get what you pay for, but on the other hand, OEM prices are massively inflated.

Been in contact with ARP today. Unlike stock head bolts, theirs are not torque to yield, so do not stretch. Therefore, provided you use the ultra-torque lubricant, they are just tightened in 3 stages up to 60ft lbs (approx. 81Nm).

Is it possiblet o re-use ARP head bolts? Their website suggests you can, provided they were torqued up correctly when installed. But does anyone have any direct experience with re-using them?

Anyone know what the difference is between a 5efhe and 4efte pcv valve? Toyodiy has the 5efhe number as 12204-10030 and is used on several engines, mainly 5e. The 4efte has a number of 12204-10040 and, although it states starlet turbo, it also states paseo and tercel engines! I'm confused. Can either used in either engine as I know they'll fit?
