Common Problems
Alfa Romeo 670050436 Engine Problems - What Actually Fails
Every engine has its weak points. Here are the known issues with the 670050436, based on real-world data and verified failure patterns.
Verified issue focus: Low-pressure fuel pump failure; secondary oil pump failure (pre-2019); oil consumption.
1. Low-Pressure Fuel Pump Failure - sudden stalling without warning
1. Low-Pressure Fuel Pump Failure - sudden stalling without warning
Typical onset:
20,000-60,000 miles (documented in 2017-2019 vehicles)
What happens:
The low-pressure fuel pump can fail without warning, cutting off fuel delivery immediately and leaving the car disabled. This issue has led to over 2,100 customer complaints, nearly 500 warranty claims, five crashes, and three injuries in the US. The recall covers 53,849 vehicles in the US and 3,300 in Canada. Affected models include 2017-2019 Giulias and 2018-2019 Stelvios equipped with the 2.9-litre V6.
Repair vs replace:
Fuel pump replacement is a standalone repair - but many owners report repeated pump replacements with no fix in sight, and the part has been on back order. A fix is still being developed as of late 2025.

2. Secondary Oil Pump Failure - cylinder shutdown codes
2. Secondary Oil Pump Failure - cylinder shutdown codes
Typical onset:
30,000-40,000 miles (early production vehicles, pre-2019)
What happens:
The secondary oil pump (auxiliary pump) can fail, with the shaft seizing and twisting. Symptoms include cylinder shutdown codes (typically cylinders 1, 2, and 3). The pump design was revised in June 2019. This affects early production QVs, with one reported failure at 35,000 miles.
Repair vs replace:
Oil pump replacement is a standalone repair costing approximately $789-$982 (parts only). If the pump fails completely and oil starvation occurs, the engine may require full replacement.

3. Oil Consumption - valve stem seals and piston rings
3. Oil Consumption - valve stem seals and piston rings
Typical onset:
40,000-80,000 miles
What happens:
Some 670050436 engines experience oil consumption, particularly on higher-mileage units. This can be caused by valve stem seal degradation or piston ring sticking, especially on cars that have been tracked or driven hard. Symptoms include blue smoke on start-up and needing to top up oil between services.
Repair vs replace:
If caught early, valve stem seal replacement is a standalone repair (cylinder-head-off job). If piston rings are the cause, a full rebuild or replacement may be more cost-effective.

How to Confirm You Have the 670050436
The 670050436 is the primary engine code for the Alfa Romeo 690T 2.9-litre twin-turbo V6, produced from 2015 to the present. It is a 90° V6 with a closed-deck aluminium block, DOHC valvetrain, and both port and direct injection. The engine is Ferrari-derived - essentially a cut-down version of the 3.9-litre F154 V8 used in the Ferrari 488 GTB. Where to find the engine code: - On the engine block - a stamped plate near the front of the V - On the V5C registration document - under engine number - Via an Alfa Romeo VIN decoder - the engine code is part of the vehicle identification Commonly confused codes: - 670052588 - a related engine code used in some Quadrifoglio models - 670052721 - another variant of the 690T engine - EED - the sales code for the 2.9L V6 engine in US market documentation - 2.0T GME - the 2.0-litre turbo four-cylinder used in non-Quadrifoglio Giulia and Stelvio models; completely different engine

Buying Guide
Buying a Replacement 670050436 - What to Choose
Choosing the right replacement route depends on your budget, risk tolerance, and ownership goals. Here's a breakdown of your options.
Used:
** A used 670050436 is a viable option given the relatively low availability of reconditioned units. However, the engine's known weak points - fuel pump and oil pump - must be addressed. Only buy with documented evidence that the fuel pump recall has been completed and the oil pump is the revised (post-06/2019) design. Used units typically cost £5,000-£6,500. Used engines
Reconditioned:
** A proper 670050436 recon addresses the engine's known weaknesses: new fuel pump (latest revision), revised oil pump (post-2019 design), new valve stem seals, piston rings (if needed), and a full gasket set. This is the right call for owners who want a reliable, long-lasting unit - the 690T is a masterpiece of engineering when properly refreshed. Expect £7,000-£9,000 with 12-24 months warranty. Reconditioned engines
Rebuilt:
** A full 670050436 rebuild is justified for high-performance or enthusiast applications where the owner wants absolute reliability and upgraded components. This is a specialist undertaking due to the Ferrari-derived architecture and complex twin-turbo system. Costs exceed £9,000-£12,000. Rebuilt engines
Supply & Fit Line:
** Our vetted UK Alfa Romeo specialists offer supply-only or full supply-and-fit - 12-month warranty on reconditioned units, nationwide delivery. Supply and fit
Vehicle Value Note:
** The 670050436 sits in Alfa Romeo Quadrifoglio models now worth £30,000-£60,000 depending on age and mileage. A reconditioned engine at £7,000-£9,000 represents 15-25% of vehicle value - a significant but justifiable investment for a high-performance car. However, given the complexity of this engine and the specialist knowledge required, ensure you have access to a reputable Alfa Romeo specialist before committing to any replacement.
