# 3801518 Longblock | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured long block for the TAD1650GE and TAD1651GE, weighing 1386 kg. The reman catalogue defines a long block as a cylinder block assembly with pistons, connecting rods, crankshaft, camshaft, cylinder heads, rocker mechanism, oil pan and valve cover, and lists no reman short block for this engine. Unlike the two-stage TWD engines alongside it, this one runs a single turbocharger, 3801406, with cylinder head 3801803, unit injector 3801263 and circulation pump 3801418 as its other reman numbers. At 1386 kg it is the heaviest of the five long blocks listed here. Supplied on an exchange basis: core deposit 3804518 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

## 🔌 Function

Carries the whole reciprocating core of the engine as one remanufactured assembly - block, crankshaft, pistons, connecting rods, camshaft, cylinder heads and rocker gear - so a worn or damaged engine can be put back into service without buying a new one.

## ⚠️ Common Signs of Failure

-   Compression down on one or more cylinders
-   Oil pushed out of the crankcase breather
-   Metallic knock under load
-   Low hot oil pressure
-   Coolant and oil mixing

## 🛠️ Service Notes

-   Order by part number against your engine's parts list - the other four long blocks here sit in the same broad weight band
-   At 1386 kg this needs proper lifting gear, pallet freight and a prepared engine bay
-   Core deposit 3804518 is charged with this unit and refunded when the old one is returned - order both together
