# 3801517 Longblock | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured long block for the TAD1641GE and TAD1642GE, weighing 997.903 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; no reman short block is listed for this engine. The catalogue puts turbocharger 3802141, unit injector 3803637, circulation pump 3801418 and cylinder head 3801395 or 3801394 against the same engines, the head depending on which serial group the engine falls in. Supplied on an exchange basis: core deposit 3804517 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

-   Volvo Penta TAD1641GE

## 🔌 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

-   Low or uneven compression
-   Crankcase pressure forcing oil out of the breather
-   Knock or rumble from the bottom end
-   Oil pressure below specification when hot
-   Coolant in the oil or gas in the coolant

## 🛠️ Service Notes

-   The same long block covers both serial groups of the TAD1641GE and TAD1642GE, but the cylinder head splits between 3801395 and 3801394, so quote the engine serial if you are ordering a head as well
-   Cure the original cause of failure before the replacement goes in
-   Core deposit 3804517 is charged with this unit and refunded when the old one is returned - order both together
