Iran Khodro Roa
The Peykan's body with a modern front end and, on most cars, the same pushrod OHV engine the Peykan itself used — which is the single most useful fact about it, because a Roa is mechanically a 1960s Rootes design wearing 2000s panels. Rootes and Peugeot material for that engine describes the hardware; nothing filed under the Roa's own name does.
It is a pushrod engine in a car sold into the 2010s. There is no camshaft in the head, valve clearances are set mechanically, and the service intervals belong to an older era. On the carburetted and early-injection cars there is very little for a scan tool to read, so diagnosis is compression, ignition timing and fuel delivery rather than data — establishing which system is fitted is the first step, not an afterthought.
Given the age and the mileage of the surviving fleet, corroded earths and a worn distributor account for a large share of running complaints, and a bi-fuel conversion — very common in its home market — adds a gas side whose faults present exactly like petrol-side ones.

- 1.7 — OHV · petrol · 64–66 kW (86–88 hp) · 135–140 Nm (100–103 lb-ft) · a pushrod engine in a car sold into the 2010s — valve clearances are set mechanically. The Roa Sal replaced it in 2009 with the bi-fuel-capable OHVG2. **The span is under review and is kept only because narrowing it rests on one source.** en.wikipedia assigns 135 Nm to the 1600 and 140 to the 1700, which would make the lower end of this row another engine's figure; fa.wikipedia puts the same 61/66 kW split down to trim — Roa against Roa Sal — rather than displacement, so the two trees disagree about what the split even means. The es, pt and Scots articles all state 61 kW and 135 Nm labelled *(1700)*, and they are degraded copies of the English one rather than three confirmations of it

Service information
Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
