What's inside
Chain, not belt
OHV pushrod design with a timing chain. No scheduled belt job, ever. What the chain and gears sound like when they're tired, and when to look.
Carb, distributor and tune
Old-petrol discipline: carburettor, Denso ignition and cooling. The tune-up routine that keeps a Y engine sweet, and the figures to verify against your engine plate.
Part numbers we trust
Shelves are thinner for these engines. We list what's still genuine, what crosses over from the forklift world, and what to avoid.
Honest dollar values
Real NZ costs for a tune-up, cooling refresh and the jobs a 30-year-old petrol four actually needs. No padding.

I built this guide by cross-checking Toyota's factory manuals against the 8,500 owners in the Surf Syndicate community. Every fault, every fix, every part number we've tested.

A few quick answers
Is it really free?
Yes. No catch. Free PDF, delivered to your inbox in the next couple of minutes.
Why are you giving it away?
Because we sell parts for these trucks. We'd rather you keep yours on the road for another decade than have you get burned on a bad repair.
What's the 10% off code for?
Anything on surfsyndicate.co.nz that fits your 3Y or 4Y. Good for one year, one per customer.
Will you spam me?
No. Expect a handful of emails to help you look after the truck, then very occasional updates. Unsubscribe anytime.
